    Thank You, once again the remote is operational. At the auto stor they had a kiosk that allows you to test your remote to see if you need a new battery. I pointed my remote at the kiosk and it worked so I didn't get a new battery.

Try this solution out to get your keyless remote system to open your 2006 Hummer H3 door

1. Close all the vehicle doors.
2. Insert the ignition key into the ignition lock cylinder - do not turn ignition switch.
3. Press and hold the DOOR unlock switch (This is the switch on the door, NOT the remote).
4. While holding the DOOR lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF two or three times. If the door lock clicks after the second ON, OFF cycle do not do it a third time.
5. Release the DOOR unlock switch. The doors will lock and unlock one time to confirm the program mode is activates.
6. Simultaneously press and hold the LOCK button and the UNLOCK button on one keyless remote for approximately 15 seconds, the doors will lock and unlock to confirm the programming of that transmitter.
7. Repeat the previous step to program up to four transmitters.
8. Turn the ignition switch to the ON (one more click forward) position in order to exit the keyless entry transmitter mode.
9. Operate the transmitter functions in order to verify correct system operation.

If the key fob was ever dropped the solder resistor tends to come loose and eventually it quits working for the solder joint breaks off the circuit. Open the for and look to see if it broken off. It can be resolder if you have the small gun and some flux

From the clicking sound and the fact that alot of your cars systems are down i would say that your battery is dead, if not bad altogether, or a terminal is loose on the battery. Check the terminals on your battery (be careful with the + (red) side and do not touch anything else metal on the car or the - (black) pole while touching it or just disconnect the - (black) for safetys sake). Check the terminals for looseness or corrosion and repair as neccisary. Then try a jumpstart but do not let the car "click" too much or you will burn out your starter. If your car's battery is indeed dead/bad you will find out within the next few times you try to turn on your car (it simply wont turn on) take the battery to a auto parts store and ask them to do a test. If the battery is ok then you can have it recharged if its bad then you will need a new one.

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.
