Car Alarms: remote start/keyless entry, key less entry, keyless entry

Question
I have a python remote start with the starter kill. it was installed on my truck years ago (at least 4 years) but now the remote start will not work it doesn't start and the light wont flash, The other problem is that the key less entry will not unlock the passenger door any more. I checked out the wiring its fine. What could the problem be please help Thank you  

Answer
You probably lost programming on the transmitter
and will need to re do it. Go to www.directed.com and
look up your alarm to get the reprogramming info.

Then if no joy, the alarm may have troubles
you will need to repair. But I am leaning towards
lost programming here, so try that first.

Good luck.
