Chevrolet Key Replacement, Key Fob Programming & Smart Key Service
From KOBLEAR1XT truck remotes to PEPS push-to-start smart keys, we cut and program Chevrolet keys and fobs at your location across Palm Beach County.
Chevrolet keys have moved through several GM systems, from early transponder remotes on the B106 and B111 keyways to flip-key remotes and today's PEPS passive-entry push-to-start smart keys. Each generation needs a different blank, immobilizer match, and programming approach, so identifying the year and ignition type correctly is the first step in any Chevrolet key job.
Our mobile techs carry blanks, cutters, and programming tools for the most common Chevrolet lines on the road in Palm Beach County, including the Silverado, Tahoe, Equinox, and Suburban. Because Chevrolet shares the GM platform with GMC, Cadillac, and Buick, we confirm the exact fob by VIN or the original key before we cut, and we tell you the price before we start.
Chevrolet key types by generation
Chevrolet 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.
2000 to 2007: transponder remote keys
Full-size trucks and SUVs used GM transponder keys on the B106 keyway with remote head and KOBLEAR1XT remotes. The chip talks to the GM immobilizer, so a blade that fits the lock still will not start the engine unless the transponder is matched.
2008 to 2018: remote head and flip-key remotes
GM moved many models to remote head and flip-key remotes such as the OUC60270 family on trucks and SUVs and the OHT01060512 family on cars. All-keys-lost work in this era is done by OBD with the right security access.
2015 to present: PEPS push-to-start smart keys
Push-to-start Chevrolets use PEPS (passive entry push start) smart keys such as the HYQ1EA and HYQ4EA on SUVs, with HYQ1AA flip-key remotes on recent Silverado trucks. Replacing a lost smart key requires programming to the specific vehicle.
Chevrolet 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.
Chevrolet Silverado Key Replacement
The Silverado is the most common Chevrolet truck we make keys for in the county. Its key system changed roughly every few years, so the year and whether it is turn-key or push-to-start determine the blank and fob.

Chevrolet Key & Fob FAQs
Can you make a Chevrolet key if I lost all of them?
Yes. We generate and program a new key or smart key from 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 Chevrolet PEPS push-to-start smart keys?
Yes. We supply and program PEPS proximity smart keys such as the HYQ1EA and HYQ4EA on Tahoe and Suburban and cut the emergency insert blade.
Is my Silverado 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 to start it is a PEPS smart key. Tell us which so we bring the right key.
What does it cost to replace a Chevrolet key?
It depends on the year and whether it is a transponder remote, a flip key, or a PEPS smart key. We give you an up-front price over the phone before we head out.
Can you cut a spare Chevrolet key from my working one?
Yes, and a spare made while you still have a working key is the cheapest key you will ever buy. We cut and program it on the spot.
Do you work on Chevrolet trucks at my home or job site?
Yes. We are fully mobile and come to your home, workplace, or wherever the truck is parked in Palm Beach County.
My Chevrolet key turns but won't start. What's wrong?
The chip in the key talks to the GM immobilizer. If the blade is fine but the engine cranks without starting or shows a security light, the transponder may have failed and the key needs reprogramming or replacement.
What information do you need to make a Chevrolet key?
The year, model, VIN, whether it is turn-key or push-to-start, and proof you own the vehicle. A photo of your existing key or fob helps us match it.
Do you replace Chevrolet flip keys where only the buttons died?
Yes. If the blade still works but the lock and unlock buttons stopped, we can replace and program a new flip-key remote.
Are aftermarket Chevrolet keys reliable?
Quality varies. We carry keys and fobs we trust to program and hold up in the Florida climate, and we will tell you honestly when an OEM fob is the better choice.
