DISABLING & ACTIVATING ANTI-THEFT SYSTEM ARMING & DISARMING (UTD SYSTEM)

Disarming Procedure

To disarm system while SECURITY indicator is illuminated and doors are still open, move electric door lock switch to UNLOCK position. To disarm system after it has been fully armed, unlock door using a key (from outside), turn ignition on (from inside) or use UNLOCK button on remote keyless entry transmitter. To deactivate alarm once it sounds, unlock a front door using a key or use UNLOCK button on remote keyless entry transmitter.

There is no reset for the system. If you are getting a message, and a no crank, you have a theft system problem. Easiest way to isolate it, is to check that the ignition cylinder is not at fault. If you know how to use a voltmeter, and can accomplish some simple trim disassembly, you can figure it out. Remove the lower insulator panel from under the drivers side of the dash. There is a large connector, that is held together with a 7mm hex bolt, disconnect that connector(it will have the flat turn signal and wiper switch connectors integrated). There is an orange wire conduit with two small white wires, that go to the wiper switch connector, two terminals on the end of the connector. Connect the ohmmeter across these two wires, insert the key, and rotate to all positions. You should see the same resistance value across all positions. Somewhere in the k(1000) ohms range. This is the resistance of the key pellet(or should be). My guess is, you are going to see open circuit at some time, or all the time. This would indicate your ignition cylinder(not switch) is faulty. Replacement requires steering column disassembly, at least below the lock plate and turn signal switch, and also requires some special tools. If you haven't, try a second key to see if you get same result. If you do, it needs a cylinder.
