That's interesting. I'll have to try it now.
I installed a keyless entry from eBay for $30 which included shipping. It was a generic kit that can have an alarm and light confirmation added later. I just wanted to stop using my key in the locks. I used the master actuator to operate the driver door lock to use the existing vacuum system for the other locks and cut out the other 3 slave actuators. It comes with two remotes and if I lost them both, it's only $30 for two more with a new receiver
. Still, a new key is only $12 from the dealer.
