FOB 8Z0 837 231 F acceptable as a replacement for 8Z0 837 231 B ??
 

I have a FOB as follows:

TEMIC-MANILA 315 MHZ
8Z0 837 231 B/357733 02/02

by battery
PA6-GF/GK30K


on chip
288537.05 L
288537.05.S


but it stopped working. Can I buy a 8Z0 837 231 F instead since B are impossible to find online?

only if the FCC id's match

that would make sense. Now where can I find the FCC ID? No where on the FOB
 

I posted all the numbers I could find except for the ones printed on the microchip.

Can you look at your key given that it is a 02 as well ;-)

Looks B is not interchangeable according to a post on AZ. F and P are
 

I am calling a few places today to see how much they are charging for the key.

Just bought a new key from keylessride.com for 79 bucks shipped.

sure it stopped working or it just needs to reprogram
