I've recently bought this vehicle (2000 Blazer 4x4 LT) and it didn't come with remote key fobs...I plan to buy some off ebay but i need to know where i find the serial # to match them up to make sure i buy remotes that will work?
Now for my main problem right now...Everything has worked fine as in with when i open the doors the int. lights come on...and when i turn the vehicle off the radio stayed playing until i opened a door....I was working on it the other nite and the battery ran dead...i got i charged up and running again...but now the int. lights stay on...and the radio shuts off when i turn the vehicle off....So i looked in my owners manual to trouble shoot and so i push in the dome overide button in and the int. lights go out but of course they don't come on when i open the doors...so i push the overide button to the out position and the int. lights come on and stay on....My understanding from the owners manual is that it wouldn't reset until i unlocked the doors with the key fob remote (but like i stated, i don't have them yet) So my question is...Is there any way to reprogram it or reset it to where the dome light overide works again? Or am i just gonna have to wait and get the remotes for it? Thanks for any info. anyone can give me...Greatly appreciated....Thanks again....
