    how do you get into it without busting the enclosure. I see no screws

  • MrsMoffitt Nov 04, 2008

    dont know how to open the key fob enclosure to change the battery

  • Anonymous Dec 01, 2008

    I keep reprogramming the fob, even the dealership has used a "special" computer and the fob won't stay programmed. The battery has been changed twice. Does anyone know what may be causing this problem? Is it likely the car or the fob?



    Note: I only have one fob and I have recently had to replace the factory radio.

    Same here. Keep replacing battery in keyless remote. alarm wont activate

  • junkie4fame Jan 08, 2009

    On the radio console there is an option to turn the remote start feature on and off. Mine worked for 2 years then just stopped, I asked the same questions then thought to check if it was disabled. Sure enough, it was! Might be worth a shot, sometime we forget to consider the simple things.

Keyless entry on honda civic 2006 not working


The keyless entry is designed to work with the doors closed (closed - not locked). If the door ajar sensor thinks the door is open the keyless entry is disabled. When you manually lock the door it might tighten the door just enough to activate the keyless entry. I would try slamming all the doors closed and then see if the keyless entry works. If it still wont work have the wiring checked on the front door lock.

Key Pad Entry does not work


does the key pad light when you press a button at night? If yes, the fuse is ok.
Do you have the plastic card with the permanent code in your owner manual packet? If yes, tryit.
report back.

Keyless Entry The keyless entry keypad is hardwired to the GEM. The GEM interprets the inputs from the keyless entry keypad and then controls the associated operation. The keyless entry keypad will be illuminated for five seconds when any button is pressed. Additionally, it will request the illuminated entry feature to turn the courtesy lamps on. If a lock all doors code is entered, the illumination will turn off, as well as request the illuminated entry feature to turn off the courtesy lamps. When pressed, the keyless entry keypad supplies the ground signal to the GEM or the GEM receives a signal from the keyless entry remote transmitter. Then the GEM outputs a ground signal to the appropriate lock or unlock relay which supplies the power to the actuator to lock or unlocks all doors, including the luggage compartment. The keyless entry remote transmitter also unlocks the liftgate or activates the panic alarm by sending a signal to the GEM.
