Replacing my daughter's radio/Satelite CD, we no longer have remote functions as door locks and alarm. The anti-theft/security module is in the old radio. Are there any quick/easy solutions to restore these functions with our existing remotes?

Use a 70-1720T harness from Metra. Do a search on google for 70-1720T and you will see what it looks like. The old radio needs to stay in the car and be powered up. The green plug that was plugged into the factory radio will also need to be plugged into it. It gets stashed behind the center console below the radio. The instructions with the harness show pictures of where the radio goes. You may also notice your dome light doesn't turn on when you open the door anymore.

you can also buy the 71-1720 and 70-1720 harness/rev. harness and make the T harness if you cant find it locally. then shove the factory deck back and under the normal radio opening.

I had already hardwired in the new stereo, But by cutting the speaker wires to the old adapter and shoving the old radio back in under the new, face first, I was able to restore the keyless features. Thanks to everyone who responded.
