Programing Remote Keyfob

You will need all the keyfobs for the system, and the ignition key.

This is valid for 3rd Gen vans, and some 2nd Gen vans, I forget particular years.

For years 1997 – 1999 ASTRO AND SAFARI VANS

Again, you need all keyfobs you are going to use, once you start programming, all others are deleted from memory.

Jump the OBD2/DLC pins 4 and 8 using a jumper wire/paperclip.

The vans locks will cycle to let you know you are entering programming mode.

Press and hold LOCK and UNLOCK on the 1st transmitter and hold until the locks cycle again, then release.

Do the rest of the keyfobs, then remove the jumper.
