Hey guys, I just have a problem with reprogramming my unlock/lock buttons on my key. I tried to program it but it doesnt seem to work. To unlock and lock, do I use the manual lock button or the power lock button on the driver's door?

Also, I have another key and I want to program it. Do I have to delete the prior program before I can reprogram it? Thanks

 

I'm also looking to how to register a new key to my 2000 gs.. I have a 99 manual but following the directions doesn't seem to work.

 

Check out my post and download the atached files 'wireless.zip'. Follow the instructions to program new key or delete old one. This is what the dealer uses to program your key.

Answer to first post:
You have to use the power lock/unlock on the driver's door to program your key.

It's only takes about 5 mins to program.
