1992 LSL security system trouble

[wohnson89]

So.. here's the deal... I just recently got a 1992 SVX LSL with the security system and the guy in Washington lost the original key or somthing so all I have is three un-original spare keys and no remote.

Today my dad was pulling it out of the shop and the alarm would not stop going off and the car wouldn't start and we have to key fob to turn it off.

How can the security system be deactivated so I can use my car?

p.s. I was in the process of taking my lights out of the car to PDR some dents (the front lights are out)
