06 GMC Passlock

Yes. Passlock is a resistance system built into the key switch. It uses an ordinary key.

Well that's actually a good move. They usually charge 3 times the value for the remote starters put in from the dealer. They have a local shop do it for them and then double the price.Steve G

GM's Passlock system uses a stationary hall effect sensor and a rotating magnet that is built into the ignition lock itself. So when you stick the key in and turn it, the magnet passes over the hall sensor and creates a resistance value that is sent to the computer. If the computer determines the value OK, the car will start. GM uses 10 different resistance values in their ignition locks.A little from column A, a little from column B.
