So I pulled my 2006 mustang V6 out of winter storage and my keyless entry fob wasn't working.
it worked before the car went away. I tried the following :
1) tried to reprogram the key fob (ignition on / off 8 times etc) with no luck
2) replaced the battery in the key fob and tried to reprogram again with no luck
3) purchased a new after market key fob and tried to program with no luck

any suggestions? The battery was low when starting the first time but the car hasn't displayed any kind of electrical symptoms and is running great otherwise.
