The keyless entry keypad is near the driver window on Ford F-150 and illuminates when you touch it. This article lists all the possible causes on why your vehicle’s keypad has stopped working.
The keypad on driver’s door of F-150 can be used to unlock your vehicle by entering a factory-set code (master access code) or your custom code if you’ve programmed it. The master access code is a factory-set five-digit entry code. You can operate the keypad with the master access code at any time. The master access code is on the owner’s wallet card in the glove box and is available from an authorized dealer.
If your Ford’s keypad is not working, then it could be due to one or more of the following reasons:
Key fob out of range
Make sure your remote control is within 3 ft (1 m) from the front door handles and the tailgate.
Stationary key fob
Keypad will not work if the remote control / key fob remains stationary for about a minute.
Dead 12v battery
The main 12v vehicle battery has no charge.
Dead key fob battery
The remote control battery has no charge. If the key fob battery is dead, keyless entry keypad will not work.
Radio-frequency interference
There is interference causing issues with the remote control frequencies. The remote control is too close to metal objects or electronic devices, for example keys or a cell phone.
Keypad is in anti-scan mode
The keypad on Ford F-150 goes into an anti-scan mode if you enter a wrong code seven times. The anti-scan mode disables the keypad for one minute and the red light flashes.
Entering code too fast
If you enter the access code too fast on the F-150’s keypad, the unlock function may not work. Slowly re-enter the access code.
