Unlike the later Ranger PCMs with integral PATS, 99 and 2000 Rangers used a separate PATS Module. If the PCM is replaced, then the PATS Module and PCM will need to be introduced to each other using a dealer tool. I'm not sure but I think that it will not be necessary to program the PATS Module to recognize your keys. If it is, it can be done during the same visit using the same tool.

Not unless you can get someone from a dealer to make a house call with a WDS, NGS+ or equivalent.

The PATS Module and PCM share security data when first installed together, making them a matched pair. After the security data sharing, these modules will not function in other vehicles unless reprogrammed. There is a special procedure that must be carried out using the dealer tool if either the PATS Module or PCM is replaced.

rwenzing is right, you will need to take it into a dealer or someone with an NGS or equivalent computer to "re-introduce" your computer to the PATS system. Some mechanics have the computers so you may not have to go to the dealer, shop around.

It was $150 for me for 1 key cut and programmed. That sounds about what it would cost here.
