How to Program a 1999 Chrysler 300M Keyless Entry Remote Fob Smart Key
Step by Step How to Programming Instructions:
ATTENTION: You MUST HAVE one working remote to add one more to the system. If you do not have one working remote right now then these instructions will not work. You will have to have a Locksmith use a computer to program the first remote for you.
1. Turn ignition to run position (as far as you can go without starting engine).
2. Using any Working remote, press the UNLOCK button for 4 to 10 seconds.
3. Within the specified 4 to 10 seconds, continue pressing the UNLOCK button and press the PANIC button for 1 second and release both buttons at the same time. A chime will sound within 3 seconds to indicate that the vehicle has entered remote programming mode.
4. Within 30 seconds of the chime, press any button on all remotes to be programmed including previously programmed remotes. A chime will sound after each remote is programmed.
5. Turn ignition to OFF and remove key.
6. Test all remotes.
