Lost GM keys, spare keys and key fobs, cut and programmed at your car. No tow, no waiting on the dealer, and a price before we come out.

General Motors builds Chevrolet, GMC, Buick and Cadillac, and built Pontiac, Oldsmobile, Saturn and Hummer. They share key systems, so the same tools and know-how cover all of them.
Einstein Locksmith is a mobile locksmith based in Boca Raton. We come to wherever your GM is parked, cut the key, program it to the car, and you drive away. Call or text (561) 561-5397 with the year and model and you get a price before we come out.
Which key your GM uses decides how it is made. Years are approximate and vary by model.
| Years | Key type | What it means |
|---|---|---|
| Late 1980s to 1990s | VATS key | A metal key with a small resistor pellet in the blade. The pellet value has to match the car, so a hardware-store copy will not start it. |
| About 1997 to 2000s | Transponder (chip) key | PK3 and PK3+ keys with a chip in the head. Some 2000s GM trucks and SUVs used a plain cut key with the security in the ignition instead. |
| About 2010 on | Flip key and remote-head key | The remote and the chip key in one piece. |
| About 2010 on | Push-button smart key | A proximity fob that stays in your pocket. It is programmed to the vehicle through the diagnostic port. |

A dealer add-a-key for a GM vehicle typically runs about $350 to $500 all-in, and the vehicle has to get to the dealer first.
A typical dealer charges about $250 just to program a GM key, before the cost of the key itself.
With us there is no tow and nothing to order in most cases. Our price is typically well below the dealer’s, and you get it before we come out.
