I have a 06 accord and the keyless entry system will not hold the programming for any remote. Once I go through the programming steps the remote will work but only for about a minute or so. Also when locking the car with the key from the outside only the drivers side locks. I took the car to automotive locksmith who had never seen this issue before and advised me to go to a dealer. Any ideas as to how to go about this issue without going to a dealer?
