I also have the factory alarm on my 89 SC along with an after market alarm. The factory alarm didn't come with a key pod, you have to put the key in the ignition & turn the key on to disable the alarm. Sometimes I use both of my alarms! :lol:I have a 89 mr2 mk1 aw11 and I bought an alarm system that is almost here to be installed when getting ready to install it I noticed the car has a Toyota factory alarm system. I figured I would contact the dealer and see if I can get a replacement key pod for the Toyota factory alarm. When I called them and gave them the vin they told me there was no factory alarm add on for that car. I am wondering if any mk1 owners out there have a Toyota factory alarm in there car and if there is somewhere I can get a key pod or if it would be easier to remove and install aftermarket alarm system?
