U need to reset security system (pass lock II). Turn key to on right b4 cranking but don't start and let security light flash for about 10-12 mins until it stops and then turn key back off, repeat procedure two more times don't actually turn key far enough to start during first two 10-12 min cycles, third cycle though after flashing stops turn the rest of the way forward for it to start. This should then reset security and solve problem sometimes only takes two cycles to reset. Good luck, hope this is helpful & solves problem.

SOURCE: 2002 GMC ENVOY GARAGE DOOR OPENER

You have a quick fix item. There is a send code button on your garage door opener. You simply have to press that button, and within 5 secs, press and hold the button on the garage door opener (your car or other) until the opener rapidly blinks. The garage door and the opener will share info,,, and presto,, you can open by the remote opener. Take a peek at your garage door opener instructions. You can have up to three settings at one time... one for each button. I was asked if the buttons ever got the openers mixed up,, and the answer is absolutely not.

Take your Envoy to a competent mechanic and have it checked for OBD codes, etc. Otherwise, you are just replacing parts at random without identifying and solving the real problem(s).

Car alarm goes off when I use the key to open doors or start engine on my 2006 GMC Envoy. Problem started when I installed new battery.


Not familiar with the envoy, but most all GMC trucks have a alarm reset button under the dash by the steering column to reset after battery problems. Why did you change the battery? It may also be your starter has shorted out which will set off the alarm. Good Luck

2006 GMC Envoy.. Changed the battery, and now the A/C will not blow out the front vents. Works on defrost and on the floor, and in the back. What's the deal?


the deal is that your a/c doors are now out of calibration. disconnect battery for 1 minute, hook battery back up. now turn key on, DO NOT START THE ENGINE, let it set for 2 minutes, now start engine, it should now work.
