Prolock security system

How do you disable the prolock security system on a 1997 Buick Lesabre? he car has both the PASS key and the prolock system, twice before it would not start for my daughter, but started right up when I tried, now the car does not turn over with both the chip and key in place. I believe the prolem is the prolock security sysrem and want to deactivate it.

Looks like Loctronics is out of business. I found this reference for you- that may help to remove your system.

The alternative is to buy the installation instructions for your specific version of the system and reverse the order to remove it. These guys sell the manuals-
