Would an 89 SE have an alarm system and if it does how do you get the code number for the door handle keypad?

 

You can program it yourself....use the search for " keyless entry" and you should find something. The actual keyless box is on the passenger side behind the glove box over to the right. It will have the master code on it. The easiest way is to take out the box and you can get a good view of the keyless entry box and numbers.
