The 2021 GMC Sierra typically uses a proximity smart key with push-to-start and keyless entry. We identify your exact key type, then cut and program a replacement so your vehicle starts, locks, and unlocks the way it should.
We come to you anywhere in Pinole: your driveway, a parking lot, work, or roadside. With proof of ownership, we can even make keys when every key is lost.
Programming a modern key is precise work. Our mobile units carry the equipment to cut and code the correct key for your vehicle on site, which is why we can usually get you driving again without a tow.

2021 GMC Sierra key technology
The 2021 GMC Sierra generally relies on a proximity smart key with push-to-start and keyless entry. That matters because the replacement has to be both cut correctly and programmed to the vehicle — a hardware store copy alone will not start the engine on a chipped or proximity system.
Our mobile unit carries the equipment to handle proximity smart key work for the 2021 GMC Sierra in Pinole, so you are not stuck waiting on a dealer appointment.
Keep proof of ownership handy. For any key replacement, especially all-keys-lost jobs, a professional locksmith will ask for documentation showing the vehicle is yours. It protects you against theft and is a sign you are dealing with a reputable pro.

Avoid a lockout: get a spare GMC key
If your key or fob is starting to feel unreliable — sticking in the ignition, intermittent remote, worn buttons — do not wait for it to fail completely. Addressing it early is almost always simpler than dealing with a total failure at the worst moment.
The single best thing you can do to avoid a stressful, expensive day later is to make a spare while you still have a working key. All-keys-lost programming takes more time and costs more than simply cutting a spare — a small step now that saves a lot later.
GMC key replacement cost
Cost depends on the exact key technology your 2021 GMC Sierra uses — a basic transponder key is very different from a proximity smart fob — plus whether it is a spare or an all-keys-lost job. Call (408) 755-3415 with your year and model for an accurate quote.
An all-keys-lost situation typically costs more than cutting a spare, simply because it requires additional programming. It is one more reason a spare key made today is such a smart, money-saving move.
Car key pricing varies more than people expect, because the key itself does. A basic transponder key, a remote head key, and a proximity smart fob are very different pieces of hardware, and programming complexity differs by vehicle too.
