If the door is open. or any door is open. All doors will lock but the drivers door. I guess so you don't leave keys in. That's how it works on my 99.
It might be that something has gone wrong with the physical power lock button in the car - the remote will continue to operate the power lock in that case. (Also, please accept my condolences, as a former Blazer owner, for having to be involved with a Blazer.)
on my 1996 it is on your left
how do you program your keyless remote for 2003 Chevy blazer
Not sure which avalanche you have but I have the 03 Northface all you have to do to switch drivers is switch that remote you open the doors with.. On my friend's there was a driver one and driver two option on a button on the drivers door.
Press the button with a picture of a car with the trunk open. It is located on the drivers door near the map pocket. Or you press the button on your remote key.
Get in the car, put the key in the ignition. Turn the key from acc to on 6 or 7 times, the car will honk when you get in "programming mode" When its in the mode, press a button on each remote( doesnt matter which button) once, make sure to do each remote, then turn the key off.
there is a little button on the remote that should say POWER. press that and it should turn on. if it doesnt, check the batteries in the back casing of the remote. an alternative is to go up to the TV and press the power button. it should look like an O with a line half way through the top.
You push the key remote unlock button two times.....
1. Insert key 2. Hold down drivers side unlock button 3. Turn ignition to on position and back to off position three times (on,off,on,off,on,off) 4. release unlock button. (door locks will cycle) 5. hold down the lock and unlock buttons on the remote at the same time. (locks will cycle again) 6. Remove key, the remote should now work (unless is is not the right frequency for your car, in which case the locks wouldn't have cycled the second time)c
To program a 2007 GMC Envoy remote, close all the doors. ?æInsert the key in the ignition while holding the unlock button on the drivers side. Turn ignition from on to off twice. ?æNow release the unlock button. ?æThe fob is ready to program.
For Security so as nobody can jump in uninvited while you are getting yourself comfortable. Try pushing the button 2 or 3 times to unlock all doors.
The button just above green square on the bottom of remote.
