Hello i just bought a 2001 ford f150 xlt triton v8 and sometimes the theft light comes on. Not sure why and when i start the truck there is 5 beeps then a little while later 5 beeps again also dont know if its related but my cruise control doesnt work and my power door locks it didnt come with a fob but whrn i press the lock button inside the cab nothing happens. If anyone could help i would appreciate it
