How to Remove a 1999 Blazer Garage Code
- 1). Enter your Blazer with your ignition key and turn the ignition to the "ACC" position.
- 2). Press and hold the two outer buttons on the onboard remote system to activate the remote. Hold the two buttons until the LED light on the system starts flashing.
- 3). Press and hold the "Training" button on the remote until the LED light on the system stops flashing. This is done in place of syncing a remote to the system, and this will clear the programming sequence to include no remote codes.
