On exit of the Crossfire it appears there are only 2 choices to lock it.

1. With the lock button on the fob.
2. With the key in the door.

All other cars we own or have owned with power locks, there was a switch on the inside of the driver and passenger doors, that you could lock as you were getting out.

Am I missing something?

I try pushing down on the plunger lock stem but it will not go down by hand. It goes down by the fob and key.

I don't like to lock with the key, and the fob buttons are black on black and hard to read. Fobs should all be built the same. Its hard enough grabbing the right keys for the car of the moment.
