2004 GMC Envoy Remote Replacement - Fast, Affordable & Professional
Got a call from a woman near Santa Barbara City College who was sitting in her 2004 Envoy watching the SECURITY light blink on the dash. Engine cranked fine but would not fire. She had already replaced the battery in her remote thinking that was the issue.
I told her the remote and the starting system are two separate things on this truck. The MYT3X6898B fob handles door locks and the rear hatch. Starting is controlled by Passlock II, which reads a Hall-effect sensor built into the ignition lock cylinder. The key has no chip. It is just a standard cut B102 blank.
When I got there, I ran a 10-minute security relearn through the ignition. Turn to ON, wait for the SECURITY light to go solid, cycle off, repeat two more times. Three 10-minute cycles. On the fourth turn the engine caught and ran. The Passlock sensor was reading correctly; the BCM had just lost its learned value, which happens on these trucks when a battery goes dead or gets disconnected.
While I was there I opened up her remote. The CR2032 she put in was fine, but one of the contact tabs inside the fob housing was bent flat. Straightened it, tested lock and unlock from across the lot. Solid range again.
She thought the whole truck was dead. It was 30 minutes of relearn and a bent battery clip.

“Tim is a hero. He programmed a master proximity key for a newer Volkswagen that multiple locksmiths refused to touch. He spent hours until late at night making sure every function worked perfectly. The skill level here is incredible.”
“Very professional and extremely affordable. The price was literally about three times cheaper than what my dealership quoted me. Fast service and no stress at all. Highly recommend.”
“A friend lost my Lexus key and he was able to program and cut a brand new one within 20 minutes. Arrived within about 40 minutes and was friendly, efficient, and quick.”
