Aston Martin Key Replacement, Key Fob Programming & Smart Key Service
From the sapphire ECU glass key of the DB9 era to today's Mercedes-derived proximity fobs, we help West Palm Beach Aston Martin owners with keys, fobs, and honest guidance on what needs dealer-level access.
Aston Martin is an exotic, low-volume British marque, and its electronic key systems reflect that. Early modern cars used the famous ECU (Emotion Control Unit), a sapphire-crystal key you press into the dash to start. The current generation of cars - DB11, DBX, Vantage, and DBS - was developed during Aston Martin's technical partnership with Mercedes-Benz, so the electronics and immobilizer architecture behave much like a modern Daimler smart-key system. That heritage matters because it sets honest expectations: many Aston Martin key jobs, especially all-keys-lost, need dealer-level access or specialized equipment.
We are a mobile locksmith serving West Palm Beach and all of Palm Beach County, and we are straight with exotic owners up front. For an Aston Martin we will confirm what year and model you have, whether you still have a working key, and whether the job is something we can do on site or something that genuinely belongs at a franchise dealer. We never guess on a six-figure car, and we never write down a part number or chip we have not verified from your specific vehicle.
If you are locked out, have a fob that has stopped talking to the car, or simply want a spare before something goes wrong, call us first. We will tell you honestly whether we can help curbside in Palm Beach County or whether the smarter move is dealer programming - and we will give you the price before any work starts.
Aston Martin models we service
Aston Martin key types by generation
Aston Martin keys changed significantly from one era to the next. The right blank, chip, and programming path depend on the year, trim, and ignition type, which is why we ask for the details before selecting a key.
Mid 2000s to early 2010s: ECU sapphire glass key
DB9, Vantage, Rapide, and Virage era cars used the Emotion Control Unit, a crystal-topped key you insert into the dash and press to start. It carries an immobilizer transponder, and a lost ECU key is a specialized order-and-program job, not a quick cut.
Early to mid 2010s: transitional remote keys
As Aston Martin modernized, some cars moved toward conventional remote and bladed key arrangements with an immobilizer transponder. The exact setup varies by model and market, so the original key should always be confirmed before ordering.
2017 to present: Mercedes-derived proximity smart keys
DB11, DBX, Vantage, and DBS were engineered alongside Mercedes-Benz electronics, so they use proximity smart keys with a push-button start and a mechanical emergency blade hidden in the fob. These behave like a modern Daimler immobilizer system and frequently require dealer-level access for all-keys-lost.
Aston Martin key data by model
Verified blank, chip, and FCC references are marked accordingly. Where a value depends on trim, button count, or production date, confirm it from the original key, a VIN lookup, or a supplier catalog before cutting or ordering.
Data is drawn from professional locksmith key references. It is a starting point for identification, not a guarantee for your specific vehicle.
Aston Martin DB11 Key Replacement
The DB11 is the grand tourer that launched Aston Martin's modern, Mercedes-influenced electronics era. It uses a proximity smart key with push-button start, so the year and a working original key drive what is possible.
| Year range | Key type | Ilco / keyway | Chip / system | FCC / OEM | Programming | Emergency / service key | Source confidence |
|---|---|---|---|---|---|---|---|
| 2017-2025 | Smart key (proximity) | Confirm the exact keyway and blade from the original key. | Proximity smart-key immobilizer; confirm the exact chip from the original fob. | FCC ID varies by year and market; confirm from the original fob or the VIN. | Dealer-level or advanced equipment often required; all keys lost may need towing to a dealer. | Mechanical emergency blade hidden in the fob. | Needs VIN confirmation |
- •The DB11 shares immobilizer architecture with Mercedes-Benz; we treat it as a dealer-leaning job and tell you up front when a franchise dealer is the right call.
- •Adding a spare while you still hold a working key is far simpler than an all-keys-lost situation on this car.
Aston Martin DBX Key Replacement
The DBX is Aston Martin's SUV and the most likely model we see daily-driven around Palm Beach County. It uses a proximity smart key built on Mercedes-derived electronics, so confirm the year and whether you have a working key.
| Year range | Key type | Ilco / keyway | Chip / system | FCC / OEM | Programming | Emergency / service key | Source confidence |
|---|---|---|---|---|---|---|---|
| 2020-2025 | Smart key (proximity) | Confirm the exact keyway and blade from the original key. | Proximity smart-key immobilizer; confirm the exact chip from the original fob. | FCC ID varies by year and market; confirm from the original fob or the VIN. | Dealer-level or advanced equipment often required; all keys lost may need towing to a dealer. | Mechanical emergency blade hidden in the fob. | Needs VIN confirmation |
- •As a daily-driven SUV, the DBX is the Aston Martin most likely to need a spare fob or a battery service; we can advise on both.
- •Because it leans on Mercedes-Benz electronics, all-keys-lost work usually means dealer-level access.
Aston Martin Vantage Key Replacement
The modern Vantage is the brand's compact sports car and shares the current proximity smart-key system. Older Vantage models used the ECU sapphire key, so the year completely changes the conversation.
| Year range | Key type | Ilco / keyway | Chip / system | FCC / OEM | Programming | Emergency / service key | Source confidence |
|---|---|---|---|---|---|---|---|
| 2018-2025 | Smart key (proximity) | Confirm the exact keyway and blade from the original key. | Proximity smart-key immobilizer; confirm the exact chip from the original fob. | FCC ID varies by year and market; confirm from the original fob or the VIN. | Dealer-level or advanced equipment often required; all keys lost may need towing to a dealer. | Mechanical emergency blade hidden in the fob. | Needs VIN confirmation |
| 2006-2017 (ECU era) | ECU sapphire glass key (immobilizer) | Confirm the exact key style from the original; the ECU is a specialized order, not a standard blade. | Immobilizer transponder in the ECU; confirm the exact chip from the original key. | FCC ID varies by year and market; confirm from the original fob or the VIN. | Dealer-level access typically required; ECU keys are ordered and programmed, not cut on the spot. | Confirm emergency access details for your specific car. | Needs VIN confirmation |
- •Tell us whether your Vantage uses a glass ECU you press into the dash or a modern proximity fob; they are completely different jobs.
- •ECU sapphire keys are a specialized, lead-time order and almost always a dealer-leaning job.
Aston Martin DBS Key Replacement
The DBS is the flagship super-GT and uses the current proximity smart-key system shared across the modern lineup. As a flagship exotic, we approach it conservatively and tell you when a dealer is the right answer.
| Year range | Key type | Ilco / keyway | Chip / system | FCC / OEM | Programming | Emergency / service key | Source confidence |
|---|---|---|---|---|---|---|---|
| 2018-2025 | Smart key (proximity) | Confirm the exact keyway and blade from the original key. | Proximity smart-key immobilizer; confirm the exact chip from the original fob. | FCC ID varies by year and market; confirm from the original fob or the VIN. | Dealer-level or advanced equipment often required; all keys lost may need towing to a dealer. | Mechanical emergency blade hidden in the fob. | Needs VIN confirmation |
- •On a flagship exotic like the DBS we never guess; we confirm everything against your VIN and original key before quoting.
- •All-keys-lost on the DBS typically belongs with dealer-level programming, and we will say so plainly.
Common Aston Martin key problems
- •Lost or failed proximity fobs on DB11, DBX, Vantage, and DBS that need dealer-level programming.
- •Owners surprised that the older Vantage and DB9 era ECU glass key is a specialized order rather than a quick cut.
- •All-keys-lost situations on Mercedes-derived models that usually require towing to a franchise dealer.
- •Weak or dead fob batteries that cause a no key detected message even with the fob in the cabin.
- •Salt air and humidity from coastal Palm Beach County driving affecting a fob's electronics over time.
- •Owners wanting a spare before something fails, only to learn a spare on an exotic still needs proper programming.
- •Mechanical emergency blades that are rarely used and have never been tested for a real lockout.
Aston Martin programming notes
- •Adding a spare while you still have a working key is far simpler and cheaper than an all-keys-lost job on any Aston Martin.
- •Modern DB11, DBX, Vantage, and DBS use Mercedes-derived immobilizer electronics, so all-keys-lost frequently requires dealer-level access.
- •ECU sapphire glass keys from the older Vantage and DB9 era are ordered and programmed as a specialized job, not cut on the spot.
- •Proximity fobs are bound to one specific vehicle and cannot be moved to another Aston Martin.
- •We confirm the exact key details against your VIN and original key before ordering anything for a six-figure car.
- •We tell you honestly up front when a job genuinely belongs at a franchise dealer rather than curbside.

Aston Martin Key & Fob FAQs
Can you make an Aston Martin key if I lost all of them?
Sometimes, but be honest with yourself about the car. Modern DB11, DBX, Vantage, and DBS use Mercedes-derived electronics, and all-keys-lost on these often requires dealer-level access or even towing to a franchise dealer. We will tell you plainly whether we can help curbside in Palm Beach County or whether the dealer is the right call.
Do you program Aston Martin proximity smart keys?
For some situations, yes, but the modern lineup leans heavily on dealer-level programming. We confirm the year, model, and whether you still have a working key before promising anything, and we never guess on an exotic.
What is the ECU glass key on my older Aston Martin?
The Emotion Control Unit is the sapphire-crystal key on DB9 and older Vantage era cars that you press into the dash to start. It is a specialized order-and-program item, not a key we cut on the spot, and it is almost always a dealer-leaning job.
Is my Vantage a glass ECU car or a proximity fob car?
It depends on the year. Older Vantage models use the ECU sapphire key you push into the dash, while the modern Vantage uses a proximity fob with push-button start. Tell us which one you have because they are completely different jobs.
What does it cost to replace an Aston Martin key?
It depends on the model, the year, and whether it is a spare or an all-keys-lost situation. Exotic keys are a serious item, and we will give you an honest up-front price before any work starts.
Can you cut a spare from my working Aston Martin key?
A spare made while you still have a working key is always the simplest path, but on an exotic it still needs proper programming. We will confirm what your specific car requires before we commit.
Do you come to my home or storage location in Palm Beach County?
Yes, we are fully mobile and serve West Palm Beach and the surrounding county. For an Aston Martin we will confirm in advance whether the job can be done where the car is parked or whether it needs to go to a dealer.
My Aston Martin shows no key detected. What is wrong?
Most often it is a weak or dead fob battery, so that is the first thing to check. If a fresh battery does not fix it, the fob itself may have failed, which on these cars usually means dealer-level programming for a replacement.
Why do you keep saying the job might need a dealer?
Because we would rather be honest than waste your time and money. Aston Martin is a low-volume exotic marque with locked-down, Mercedes-derived electronics, and pretending otherwise on a six-figure car would not be fair to you.
What information do you need before working on my Aston Martin?
The year, model, and VIN, whether you still have a working key, whether it is an ECU glass key or a proximity fob, and proof you own the car. A photo of your existing key helps us prepare.
Can you replace just the battery in my Aston Martin fob?
Yes, a fob battery service is one of the simplest things we do, and it solves a lot of no key detected complaints. We can advise on the right battery and check the fob while we are with you.
Should I get a spare Aston Martin key now or wait?
Get it now while you still have a working key. A spare arranged ahead of time is always easier than an all-keys-lost emergency, which on these cars can mean towing and dealer-level programming.
