Hi all:
So I have a '95 z28. Will the factory security system go weird if I take out the original stereo and replace it?
thanks
Duane

 

check to see if you have delco lock 11 or theft lock. i think you will be ok if you turn it off before removing stereo.
How to unlock a THEFTLOCK or DELCO-LOC II audio system

 

OK. The deck says ACDELCO on it and at the top of the display it says "THEFTLOCK." How do I turn off the theft lock?
thanks

tells how to disable in the link i posted.

 

LOL. I didn't see the link the first time.thanks Craby.

 

The security system for the radio is internal to the radio itself and separate from the VATS system in the car. If you plan to reuse the original radio, you will need a code to make it work again after it has been disconnected from the car. Since the VATS itself does not care about the radio, you can replace the original radio with another one of any brand, as long as it does have its own built in theft deterrent system that, in which case the instructions of how to handle it should come with the new radio. You may want to check in the owners manual, as the original owner may have written the security code down, assuming he/she read the manual.

 

thanks pete, learnt my new thing for the day.

 

You can get this code from a Dealer, but you might have to physically take the car and radio up to prove you own them. I had to do this once.

 

So just to be clear. I can take the original radio out and replace it with an aftermarket unit without any detrimental effects to the operation of the vehicle. It is only if I want to put the original radio back in that I need the security code as noted above.
Appreciate the feed back (pun intended)
thanks
Duane

 

correct, well if its a good stereo you wont be able to hear that may effect the operation of the vehicle.
