I just got a 2005 Corolla CE with the 5speed manual. It has power locks (i think) but not sure it they would be compataible with some sort of keyless entry. There is no door lock button on the arm rest however all the doors will lock and unlock when using the key in the lock cylinder. When I turn the door key all the doors will lock and unlock at once. So is there a keyless entry system that will easily install and work? Thoughts?
