I have had to replace the 2 batteries in my 2005 PS 6.0L Crewcab today since at least one of the batteries is dead. Put 2 new batteries in and when I tried to start the truck the alarm goes off. I tried to mess with the key fob but that did not do anything. Tried to start the truck but it would not crank over. The dashboard light was flashing while the alarm was honking. I ended up disconnecting the passenger side battery to make the alarm stop. I appreciate it if anyone could tell me how to reset the alarm.
Right now I have reconnected the batteries and the alarm is not sounding as long as I am not trying to start the vehicle.
Do you know the name of the alarm? Normally you have to turn the ign. on and push a button (that came with the alarm) within 15 seconds or so. Sometimes the led is also the button. Its a momentary push button. Eric
I believe that this is a factory alarm. There is a red-lighted button located below the fuse area next to the hood release. I pushed and held down on it but it did not seem to stop the alarm. I will try again tomorrow. Thanks, Eric.
Many thanks to Daddykitty and Cheezit. Let me recount what happened:
I tried what Daddykitty had suggested and the alarm stops honking. However, the engine would not crank over when I tried to start it.
The next step is to try Cheezit's suggestion. I rolled the window down and put the key to ON position. Then disconnected the batteries. Then reconnected the passenger's side battery first--the alarm honked once. Then reconnected the driver's side battery. Turned the key from ON position to start and it started right up!!!
Bud, I could not tell if this 05 PSD Crewcab has a Ford factory security system or aftermaket. However, the Owner's manual does address a "security system" and there is a separate "Security System Manual". Just that they do not tell you what to do when replacing the batteries.
My thought on this is that the alarm system wants to see the key in the ignition to perhaps prove that the owner or authorized person is working on the truck before it allows it to crank over.
Oh and Soon Rather than Later would be Best here Cause when you unhook and Hook up the bats the truck Does a Master Reset all the Gauges and everything do a Sweep and reset and I assume the PCM/TCM Does a Reset to0!!!!
Worst Case Unhook the Alarm/remote start till you figure it out
Mine is a Python alarm made by company called Directed Electronics and IIRC Has LifeTime Warrenty. And Directed Electronics make a Few Diffrent Brands so you might be in Luck
After several attempts, I have figured out the problem.
When I purchased the truck used, it came with a remote starter from Compustar that never worked properly. I tried many attempts to reset it them gave up and put it in the drawer.
To my dismay, it was actually the remote starter system that was enabling the truck from re-starting. After finding the fuse and disabling the entire after market remote start, I was able to start the truck up just fine!
What a rigermarol!
Thanks all for your help. My best advice is never to install an after market remote starter! It's more headache than what it's worth.
