J.T.'s 3.2CL

I am going to be installing a new remote start alarm in my CL soon and was wondering if I can program one of the keys from my old 2000 TL to hide in the DEI 555U key box. I would hate to go to the dealership to buy and program a new key if it's not needed. I also wouldn't want a cut key that can start the car hiding anywhere in it. The process for programming a key is below....Is their anyway I can adapt this process to make the old key work??? It says the ignition must be turned on but would it work if I put my current key in the ignition and held the old one near it? Also how would I know it got programmed? I'd hate to be in the middle of getting the alarm installed to find out the key in the transponder doesn't work. Any thoughts on this are appreciated.

Thanks, J.T.

Hop in the car have both remotes ready.Now insert the key in the ignition in the lock and cycle it to the run position.Do not start the car simply get the lights in the Instrument cluster to come on.As soon as the lights come on hit the unlock button on one of the remotes.Cycle the key to off and then back to run and hit the remote again.You will have to repeat this quickly five times using the same remote.As soon as you hear the doorlocks cycle (audible thump in the door)leave the ignition on now quickly hit the lock button on the remote,then get the other remote and hit the unlock button snd then the lock button.The car will respond by cycling the door locks.It may require a few tries to do as you have to get the trick down with cycling the key and hitting the unlock quick enough for the car to enter the programming mode.Jens

I went to the dealership and had them program me a key, but not cut it. Cost $25.00
