Key cyclinder. I've notiched a lot of new cars/trucks etc,don't have a key holes anymore.Now i haven't come across this yet because i work on pre 2000 cars but i know i will sometime. I know how to test for a disarm wire by using the key but don't know how to do it on new cars. any help would be great

If it don't have a key cylinder, it proably won't have a disarm wire. Some new cars only disarm with the factory remote (GM's), while some will disarm by remote or by turning on the ignition. A bypass module may also disarm the alarm, as well as do the doorlocks. If you have a question on a specific vehicle, let us know which one.

Some disable with key sense as well. It is still a case by case basis and you can find most disarm wires by looking up the wiring diagram as it will tell you if it is even available.

I can't recall seeing any car with no key cylinder on the exterior at all. I mean, how would you get in if the car's battery died.
They've removed the passenger-side key cylinder from almost all new cars, and a lot of them don't have one on the trunk either......but there should certainly be one for the driver's door.
The Acura RL for example.....at least I think it was an RL......appears to have no key cylinders, but on the driver's side of the car, you can remove a decorative plastic cover, revealing the key cylinder underneath.

Every Audi has a key cylinder. On the A8 it is hidden. You have to lift up the handle and look behind it.

Actually my 2005 Corvette *does* have a external key, it's above the rear license plate that allows just for that. Now being able to get into the vehicle due to a dead battery etc.
