Smart Keys in Denver Metro

A smart key (proximity key, KEYLESS-GO, Intelligent Access, Advanced Key, Comfort Access) is a fob that communicates with the vehicle over short-range radio, unlocking the doors when you approach and enabling push-button start. They became common in the 2000s and 2010s; the exact year varies by make and trim.

For many supported vehicles, yes, including various Toyota, Lexus, Honda, Nissan, Ford, Chevrolet, Hyundai and Kia models and some European models. Support is year, model and platform dependent, so I check your vehicle details first.

Service call starts at $49; smart keys usually cost more than basic transponder keys because both the hardware and the procedure are more involved. Every job is quoted before I begin.

No. Some smart keys unlock every door by touch, others only the driver's door, and remote start or power liftgate buttons appear only on equipped vehicles. A replacement key matches what your vehicle supports; it does not add features. If no working smart key remains, see the lost car keys page.

For many mainstream vehicles, yes, when the key is verified compatible. Some vehicles reject aftermarket electronics — I check compatibility before you buy.

Adding a key normally leaves existing keys working, and programming does not automatically delete old keys. Where the system supports removing missing keys, I explain what that involves; not every vehicle allows it outside the dealer.

Often a weakening fob battery, a damaged fob, or interference from nearby electronics; occasionally a vehicle antenna or module fault. I diagnose first and then replace the battery, repair or replace the fob, or refer you to a mechanic if it's a vehicle fault.

Most smart keys hide a mechanical emergency blade for door access when the fob battery is dead, though it varies by model. That blade doesn't start the engine, but it gets you inside. When your key includes an emergency blade, I cut and pair it with the new smart key.

It depends on the vehicle. Adding a smart key is usually quicker than all-keys-lost work, and some systems involve manufacturer wait periods. I give an estimate once I know the vehicle.

Sometimes. If the electronics are corroded beyond repair, a replacement may be needed. Removing the battery and drying the fob promptly improves the odds of saving it.
