KEY FOB locks/unlocks , but no turn
Hey Guys - My 01 E55 woke up after a long winter's nap, here's what I did. Battery was low , so I took out the back seat charged battery in place. Started fine , reversed out of the garage, removed battery (Walmart MAX 900CCA) to give it a deep charge. Slipped the battery back into position , connected POS,NEG terminals, and installed the seat. Put key fob in , does not turn the switch. Locking and trunk buttons work properly, as does the security alarm.
Ideas and/or things I could troubleshoot ? I changed the key fob batteries (I believe its considered a Gen2 FOB w/metal key) , red indicators on the key works , IR with camera phone test passed...
Hard to believe the key fob fails all of the sudden after battery reconnect... Fuses to check ?
Need a 2nd key FOB as well - best source?
Many thanks !
