Which Key Your Chevrolet Blazer Actually Uses
Blazers built in the mid-to-late 1990s typically use a basic plastic-head key, sometimes paired with a separate keyless entry remote carrying FCC IDs like AB01502T or KOBUT1BT operating on 315MHz. Later model years — particularly the 2019-and-up generation — moved to smart key fobs with FCC IDs such as HYQ4AA, HYQ4EA, and HYQ4ES running at 433MHz or 434MHz, with button counts ranging from 2 to 6 depending on trim. We stock all 15 documented variants for this model, so there is no guessing or special-ordering required. Learn more about the full programming process at our key fob programming page.
What Happens When You Lose Every Chevrolet Blazer Key
Losing all keys to your Blazer is the worst-case scenario because the vehicle's immobilizer has no registered key to use as a reference during programming — this is called an 'all-keys-lost' situation and it requires specialized EEPROM or OBD-level programming equipment, not just a code-cut key. A dealer will typically demand a tow and a multi-day wait; a mobile locksmith comes to you in Las Vegas 24 hours a day and completes the work in the parking lot or driveway where the Blazer sits. Check our 24-hour locksmith page if you need immediate dispatch. The installed price shown above already accounts for all-keys-lost labor on supported Blazer years.
What Changes the Price and How to Get It Done Fast in Las Vegas
The main variables are model year, key type (plastic-head remote vs. smart key), and whether it is a spare or an all-keys-lost situation — older Blazers with basic remotes are generally faster and simpler, while newer smart-key trims with higher-frequency fobs require longer programming sequences. Having your VIN and proof of ownership ready when you call shaves time off every appointment. We carry all 15 Blazer key variants on the van, so there is no waiting for a part to arrive.

Yes — a mobile locksmith with OBD-compatible programming tools can program smart keys carrying FCC IDs like HYQ4AA, HYQ4EA, or HYQ4ES directly on-site in Las Vegas.

How do I know which FCC ID my Chevrolet Blazer key fob needs?
The FCC ID is printed on the back of any existing fob you still have, or it can be identified by your Blazer's VIN and build date — your locksmith looks this up before cutting anything. For the Blazer, documented FCC IDs include AB01502T, ABO0104T, HYQ4AA, HYQ4ES, KOBUT1BT, YG0G21TB2, and several others depending on year and trim.

How long does a Chevrolet Blazer key replacement take in Las Vegas?
For most Blazer years with a spare key present, on-site cutting and programming takes roughly 20 to 45 minutes after the technician arrives. An all-keys-lost situation on a newer smart-key Blazer can take longer due to the additional security sequences involved. We dispatch 24/7 throughout Las Vegas so you are not waiting until business hours to get back on the road.
