I have a 99 LeSabre that has a factory security system. We have the right key but do not have the remote to deactivate the system once it is engaged. I have had the car for months without the system engaging but it did so last night and I cannot get the car to start. Is there a way around the system without having to purchase the remote that will allow me to reset the system.

 

As far as I know,it need a tool to reset it
