YOU CAN FINE ALMOST ANY KEYLESS ENTRY ON EBAY AND FOR A GOOD PRICE.. GOOD LUCK.........
The keyless entry receiver is under the console - behind the screens it's the temp and compass
it has to be done by the dealer. =(
It was part of an option package
I had the same problem. Google "keyless entry remote 2003 Jeep Grand Cherokee".
It requires the dealer's scan tool.
The keyless entry system must be programmed with an OBD II tool which the dealer or locksmith has. Sorry that this is not the answer your looking for, I didn't want to hear it either.
You have to program it with a DRB (Scan tool).
Not very easily, since Wranglers do not have power locks.
dealer has to do it with factory scan tool
This model never offered keyless entry. It can be made to have keyless entry with after market products.
The only way to program keyless entry is with a very expensive diagnostic tool called "Launch" or go to nearest dealer for programming.
