Car Alarms: Ford F-150, push button switch, ford f 150

Question
I have a 2003 Ford F-150 and when I brought it already had an Prestige alarm in and today while driving to engine shutdown.  The headlights, radio, and everything else worked, but the engine would start.  The battery was weak and bought a new one and once again the engine would not make a sound.  I not certain if the system have a kill switch or not, but it has both a toggle switch and a push button switch.  Not certain system I have, but on the back of the remote the part number is 5bcr05.

Answer
This vehicle has the PATS anti-theft system
in the ignition and key.
It appears you've reset the PATS.
The car does not recognise the chip in the ignition
key any longer.

The PATS (FORD'S PASSIVE ANTI THEFT SYSTEM)
needs to be reprogrammed I believe.
You can tow it to any FORD vehicle dealer
to have the service department re code it.

The trouble is in the ignition at the reader
probably, but Ford will need to determine that.

Sorry about that.
