B3055 on Chevrolet
Key Not Present
B3055 on Chevrolet vehicles indicates key not present. Au7o has documented this code across 1 Chevrolet model — most commonly on Colorado. B3055 is a vehicle access/keyless-entry body code generally defined as 'key not present.' The keyless/passive entry module sets this code when it cannot detect a valid key fob inside the vehicle during an operation that requires the key (such as a push-button start). It usually points to a low fob battery, a fob/antenna issue, or a system fault, and typically affects keyless start/entry convenience rather than vehicle safety. Typical repair costs on Chevrolet range from $250 to $700, depending on the specific model and root cause.
Common Causes of B3055
- •Dead or weak key fob battery
- •Key fob out of range or failed
- •Faulty interior keyless-entry antenna
- •Damaged wiring or connector to an antenna
- •RF interference
- •Keyless control / receiver module fault

- Passlock Ignition Switch Failure Causing No-Start and Security Light2004-2012
First-generation Colorado/Canyon trucks commonly suffer from Passlock-related ignition switch failures that trigger a crank-no-start or start-and-stall condition with the security light illuminated. Owners often report the truck starting normally after a 10-minute relearn wait, then failing again later. GM issued service information on theft deterrent and ignition switch diagnosis, and the issue is widely documented in owner complaints and forums.
