Old Dog

This is an old thread but it discusses an even older vehicle. I hope y'all might help me out over here? After putting my mom in a nursing center, I apparently inherited a vast family fortune, to the tune of one 1996 Honda Accord. It only has 338,000 miles on it! It seems to run great and it is blessed with an alarm system like yours that locks doors I want left unlocked and it randomly prevents the car from even cranking at times. The key fob transmitter looks like a pit bull puppy's toy and I can't really tell if it's functioning at all. Mostly the car will start but many times I resort to holding down on that disarm/valet switch under the dash; doing so "usually" lets it start. I want it gone. I couldn't do it myself. Would it take a Honda dealership in order for it to be uninstalled, removed, circumvented or permanently disarmed or could any decent mechanic to the job? Thanks, I hope
