Question about DEI GM Immobilizer Bypass
2003 gmc envoy Battery was changed but now dealer installed remote start not working the remote start used to work by pressing the car remote 3 times to turn on please help
Hello, What has happened is your remote has lost its programming.. Just like with most electronics, when something is reset or powered off, or even when the battery dies ....the programming software is lost. The remote has to be reprogramed either by a dealer (suggested) or by an aftermarket outsource..Hope this helps...This could help with almost all remotes.

The transmitter incorporates a small LED visible through the case which is used to indicate battery
condition. You will notice a decrease in transmitter range as the battery condition deteriorates.
Transmitter battery replacement is recommended at least every 10 to 12 months, depending upon how
frequently the transmitter is used.
To replace the battery in the APS620TX:
1) Remove the small # 0 Phillips head screw from the rear of the case.
2) Remove the rear cover to access the discharged battery paying attention to the proper polarity
3) Carefully remove and properly dispose of the discharged battery.
4) Insert the new battery, close the case, then reinstall the small case screw removed in step 1.
5) If you accidently dislodge the circuit board from the transmitter housing, be certain that the rubber
membrane is seated properly, and the buttons are properly exposed from the front view of the case,
then insert the circuit board, and return to step #4.
