Honda Key Replacement, Key Fob Programming & Smart Key Service
From HD106 transponder keys to HO03 high-security smart keys, we cut and program Honda keys and fobs at your location across Palm Beach County.
Honda keys moved through three main keyways - the older HD106, the HO01 used through the early 2010s, and the high-security HO03 found on newer models. The technology jumped from early Megamos 13 transponder chips to push-to-start proximity smart keys, so the year and ignition type decide which key your Honda needs.
Our mobile techs cut and program keys for the Honda lineup most common in Palm Beach County, including the Accord, Civic, CR-V, and Pilot. We carry the blanks and programming tools in the van, confirm whether your Honda is turn-key or push-to-start, and finish most jobs curbside in one visit.
Honda models we service
Honda key types by generation
Honda 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.
1998 to 2006: HD106 transponder keys
Early Hondas used the HD106 keyway with a Megamos 13 transponder chip. The blade fits the door and ignition, but the engine starts only when the chip is matched to the immobilizer, so a cut-only key will not start the car.
2007 to 2013: HO01 keyway and remote head keys
Honda switched to the HO01 keyway and rolled out remote head keys that combine the cut blade with lock and unlock buttons (FCC MLBHLIK6-1T on many models). Push-to-start smart keys began appearing on higher trims late in this era.
2014 to present: HO03 high-security and smart keys
Modern Hondas use the HO03 high-security keyway with proximity smart keys (FCC KR5V1X, KR5V2X, and the newer KR5T34) that carry an emergency blade inside. Lost smart keys are programmed to the specific vehicle.
Honda 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.
Honda Accord Key Replacement
The Accord is one of the most common cars we make keys for. It spans HD106 transponder keys, HO01 remote heads, and HO03 push-to-start smart keys depending on the year and trim.

Common Honda key problems
- •Worn HD106 and HO01 blades that turn the ignition but no longer reliably start the engine.
- •Smart keys that fail after water exposure following beach and boat days.
- •Dead smart-key coin batteries mistaken for a failed fob.
- •All-keys-lost situations on push-to-start models that require programming to the vehicle.
- •Remote head keys where the buttons stop working but the blade still turns the lock.
Honda programming notes
- •Adding a spare while you still have a working key is faster and cheaper than an all-keys-lost job.
- •Smart keys are programmed to one specific Honda and cannot be reused on another vehicle.
- •Newer Hondas use the high-security HO03 keyway, so we confirm the code from the VIN before cutting.
- •A no-start with a good battery is often the chip or immobilizer, not the engine, and the key may need reprogramming.

Honda Key & Fob FAQs
Can you replace a Honda key if I lost all of them?
Yes. We program a new key or smart key to your vehicle on site. All-keys-lost jobs on push-to-start models take a little longer because the key is programmed directly to the car.
Do you program Honda smart keys (push-to-start)?
Yes. We supply and program proximity smart keys such as the KR5V1X, KR5V2X, and KR5T34 and cut the HO03 emergency blade inside.
My Honda key turns but won't start. What's wrong?
The transponder in the key has to match the immobilizer. If the blade is fine but the engine won't start, the chip may have failed and the key needs reprogramming or replacement.
Is my Accord turn-key or push-to-start?
Both exist across the years. If you insert and twist a key it is turn-key; if you press a button it is a smart key. Tell us which so we bring the correct key.
How much is a replacement Honda key?
It depends on whether it is a transponder key, a remote head key, or a smart key, plus the year. We quote an up-front price before we head out.
Can you cut a spare Honda key from my working one?
Yes. A spare made from a working key is the cheapest insurance against a future lockout, and we cut and program it on the spot.
Do you come to my home or workplace?
Yes. We are fully mobile and service Hondas wherever they are parked across Palm Beach County.
Why is my Honda smart key not detected?
It is often a dead coin battery rather than a failed fob. We can test it, replace the battery, or program a new smart key if needed.
What do you need to make a Honda key?
The year, model, VIN, whether it is turn-key or push-to-start, and proof of ownership. A photo of your current key helps us match it.
Do you service Honda SUVs as well as cars?
Yes. We handle the CR-V, Pilot, and the rest of the Honda lineup, not just the sedans.
