So I used a jumper wire on pins 4 and 8 as instructed but the doors do not lock or unlock. Also the lock buttons on both front doors dont do anything, while the unlock does work. I'm thinking I need to replace a relay behind glove box or something. I don't know which one to pull. Any help would be appreciated.

Haven't done any more tinkering with this since but still looking for answer in mean time.

Are you sure it came from the factory with remotes?

Pretty sure. It'* a 99 LS.

Just to be sure, you did follow this procedure to a T correct?

Go to www.compnine.com, enter your car'* VIN, and get a listing of all the RPO codes for your car. See if it has power door locks.

Thanks for the link man. Very useful tool. I checked it out and my car does have keyless entry. Now, I need to figure out why it won't go into programming mode. The doors should lock when the jumper is inserted but no luck.

On another note. I fixed the door lock button issue, auto lock/unlock, trunk release, etc by replacing a single fuse behind glove box. Very happy with that. Love the added luxury having those features allow.

Nevermind. I just went out and tried again and I got it to program. It must have been replacing that fuse that did it.

I'm so happy I have keyless entry now as it'* my first car with this feature. Really sucks trying to find the keyhole at night and risking scraping up paint. Now I just push a button and I'm good to go. Thanks for the help!

There are a lot of conveniences we take for granted ... until we don't have them. I'm glad you sorted it out.
