How do you program a Chrysler jeep or dodge transponder chip key?

If you don't have 2 keys you'll need to call a locksmith or the dealership. Before you call the locksmith, make sure you have the four digit PIN code to your vehicle. The dealership has the PIN code and will give it to you for FREE with proof of ownership to the vehicle. The can also give you the key code which is helpful at the same time. Add a key when you already have two: 1) Insert one the programmed transponder keys into the ignition lock cylinder and turn the switch to the "ON" position 2) The key should be in the "ON" position for 5 seconds but not more than 15 seconds. Turn back to the "OFF" position. 3) Within 10 seconds, insert second programmed transponder key into the ignition and turn to the "ON" position. The VTSS ( Vehicle Theft Security System ) or Immobilizer System lamp (depending on model ) should start to flas. An audible tone will indicate the system has entered the " Programming Mode ". 4) Within 45 seconds, turn the switch to the "OFF" position. Insert the new transponder key and turn the switch to the "ON" position. After approx. 10 seconds and audible tone will sound and indicator lamp will illuminate briefly. This will let you know key has been programmed. 5) To add aditional keys, repeat steps 1 - 4.
