Keyless Entry

My girlfriend has a 1999 Olds Intrigue. Bought it used and only got 1 key with it but would like to have keyless entry. I checked the VIN# with a dealership to see if it came with keyless entry from the factory and it didn't. What I want to know if it is still installed in the car, you just have to buy the remote to use it. I know I can get a keyfob off of ebay for a decent price, but I want to make sure it is in the car before I spend the money on it. Any help would be appreciated.

Thank You.

Just have a Alarm installed and they give you 2 remotes that they program to open door trunk and work your alarm..

Chck out alarm systems by DEI. The Viper and Clifford systems are my favorite and the installer of the system will usually do all the programing for you.
