Buick Key Replacement, Key Fob Programming & Smart Key Service
From transponder remotes to flip-key and push-to-start smart keys, we cut and program Buick keys and fobs at your location across Palm Beach County.
Buick shares the GM platform with Chevrolet, GMC, and Cadillac, so its keys follow the same path from transponder remotes through flip-key remotes to today's push-to-start proximity smart keys. Identifying the year and whether the vehicle is turn-key or push-to-start is the first step in any Buick key job.
Our mobile techs carry blanks, cutters, and programming tools for the most common Buick models in Palm Beach County, including the Enclave, Encore, and Envision. Because the source data lists limited Buick-specific fobs, we confirm the exact remote by VIN or the original key before we cut, and we tell you the price before we start.
Buick models we service
Buick key types by generation
Buick 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 mid 2010s: transponder and remote head keys
Older Buick crossovers used GM transponder keys with remote heads, including the OUC60270-era system on the Enclave. 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.
2015 to present: flip-key remotes
Many Buick models moved to flip-key remotes, with the exact part varying by model and trim. All-keys-lost work in this era is done by OBD with the right security access.
Recent push-to-start trims: proximity smart keys
Newer push-to-start Buicks use proximity smart keys, but the source data lists no Buick-specific smart-key fob, so we confirm the exact part by VIN or the original key before cutting.
Buick 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.
Buick Enclave Key Replacement
The Enclave is the Buick model we most often make keys for. Older models use the OUC60270-era remote head system while newer trims move to flip-key and proximity remotes.

Buick Key & Fob FAQs
Can you make a Buick 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 Buick push-to-start smart keys?
Yes. We supply and program proximity smart keys for push-to-start Buicks and cut the emergency insert blade. We confirm the exact part by VIN or your original fob first.
Is my Enclave turn-key or push-to-start?
Both styles 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 smart key. Tell us which so we bring the right key.
What does it cost to replace a Buick key?
It depends on the year and whether it is a transponder remote, a flip key, or a proximity smart key. We give you an up-front price over the phone before we head out.
Can you cut a spare Buick 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 come to my home or workplace?
Yes. We are fully mobile and service Buicks wherever they are parked across Palm Beach County.
My Buick 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 Buick 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.
Why is my Buick 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.
Are aftermarket Buick 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.
