Hi, the P.38 powered key FOB, stopped working recently. Please advise of any party who can repair and verify signal transmission; or any source to obtain a replacement - even used in proper working order. In the meantime, I'm using the backup key with no powered key fob... yet the dash display states that the 'key battery is low'. Perhaps in this state the ECU does not recognize the powered key and does not allow the key signal? Is there a way to clear the low battery message??

Cheers, Steve

Couple of questions......
Did the fob batteries die?
Did you replace them, noting the small contact on the cover was in place before tightening it?
Does the led on the fob illuminate?
If you have changed batteries, you may need to re sync the fob.
Possibly the low battery message was triggered, and Becm is now awaiting new info from the fob?
The fobs are becoming as scare as unicorn poop, so do try to fix what you have......
Annette, in Costa Rica has mentioned being able to get a fob that will work on NAS vehicles from a supply down South. Have not gotten confirmation yet.
I am also aware that Dr Scott (Retired) Becm Guru can make a fob from another P-38 work if he can read the Becm from the other truck. I am unclear as to what the exact procedure is, or if it requires putting your Becm on the bench as well?.....Have not gotten confirmation on that one either......
The only source I am sure of would be the dealer network, HOWEVER, you will need to buy a "Kit" which is over a grand, but has 2 fobs, and the door lock and ignition lock.
Spare individual fobs from N.A. dealers are off the menu.

Appreciate quick response....batteries were replaced as soon as the low battery warning displayed...yes with the small contact. The LED light flashes and the fob has been resynced a few times. It flashes slowly at first and then quickly... Seems that the BECM is awaiting signal from the fob.. I will ask master mechanic Bill at Kensington Motors in Las Vegas about reprogramming BECM/fob codes. Heading to England in another month - surely there is an expert there on these finicky devices - if anyone knows someone?? cheers, Steve

Something to remember is that "new" batteries have been hanging on the hook for ages. Always take remote batteries from the back of the hook since they are newer. This may just be a case of buying dead batteries.

thks for taking the time to comment... I tried a few packages of batteries... even mixed the 2025 with the 2032; as the '32's might have just a little more juice. The LED shines brightly... I'll look into rebooting BECM, if that doesn't work, then I'm sending the FOB to the guy in England who services the key module/board and can test for transmission.... cheers, Steve

Don't forget to mention to him that it is for an NAS car. NAS fobs transmit on 315MHZ compared with 433 for the rest of the world.
