Can anyone tell me what battery fits the key for a 1999 E320 and where do you insert a screwdriver to pry it open?? Thanks!!
Never mind---I found out the CR2025 is the correct battery for this fob and ordered 5 of them for a total of $6.93 w/free shipping. WalMart wanted nearly $5 for one so it will now allow me to replace the batteries in both fobs. Got them from Bob's Batteries in case anyone else needs any.
