mustang, alarm/remote start removal

Typically an alarm system would be installed on the driver's side interior of the vehicle. This system would have been tapped into the ignition switch wiring running down from the key. If you remove the dash panel(s) under the steering column you should be able to locate where the harness was added that goes to the alarm. Disconnect each wire that was tapped in and insulate the factory wiring. You will also see that at least one of the wires was cut, this is the vehicle starter wire that runs from the key to the starter. This wire needs to be restored, I always recommend soldering all connections but crimp connectors should also work. Make sure that you remove all connections to the alarm and that any wires that may be exposed are insulated and mounted in a way that they will not interfere with any moving parts and do not run the risk of shorting out. Remember to take your time and follow each connection running from the brain of the system, leaving one wire connected that you are unsure of the function could cause problems in the future so be sure to remove every wire.Installer, IT support, and FFL. I need less hobbies.

when i am done will the autopage remote do anything anymore or will i have to buy a ford remote to unlock the doors, open the trunk, and panic.

If you remove the alarm - the remote will do nothing. You would have to buy a Ford remote... if your car cam with keyless entry - the local dealer can tell you from the vin number. If your car did not come form the factory with keyless any reputable alarm/remote starter installer can install a keyless only unit for you. Actually any good alarm/remote starter installer could "deactivate" all of the "alarm" features of your current alarm and leave only the keyless entry.
