My key fob won't lock or unlock my 06 H3 but it turns the security system on and the lock buttons inside don't work and the driver window won't roll down but all the rest do.

 

Master switch needs reset.

 

How do you reset the master switch?

 

You disconnected the battery, or it died you replaced it/charged it? Do a search!

Your fob may need reprogramming and your driver door window thing happens when you loose connection to a fully charged battery. Not unusual for older I5s to loose communication with the key fobs.

 

First:
Check battery terminals(make sure good quality-non oem, clean, & secure tight)
Check battery resting voltage (12.4v+ recommended)

NOTE: RKE will not control door locks until the master switch is operating properly.

The only way I have ever been able to reset:

1- Press unlock on the rke, open drivers door
2- Remove master switch and disconnect
3- Close door and press lock on the rke
((((((((((( WAIT FOR IT.... NOT SURE HOW LONG IT TAKES, I JUST TAKE THE SWITCH INSIDE MY HOME AND WAIT OVERNIGHT))))))))))
4- Press unlock on the rke and open drivers door
5- Connect master switch connectors
6- Start vehicle
7- All works now, including the RKE.

 

Yes, disconnecting the battery or if battery runs low voltage -12.0v! The rke theft deterrent system will work again when back to +12.0v, yet the master switch is still disabled(unable to lock the doors). Therefore the horn sounds, when theft deterrent is enabled with the rke, after a door is opened. Take whatever you want, and after a few minutes the alarm will stop, yet you still can't steel my ride. The ignition switch prevents any attempt to starting the vehicle, without the proper way to activate the ignition switch. The master switch never made sense to me! I never had to look inside the master switch, still OEM. One day, if I'm unable to reset, I will open it up and analyze. In the meantime, my doors lock with theft deterrent enabled.

 

I just had this same issue with my 06 H3 yesterday. Just want to say thank you to everyone on here who posted helpful info. Without this forum I would have been in a tail spin. Ended up disconnecting the positive cable for about 30 min. fixed my issue.

 

Agree that good battery (and ground) is essential on the H3 humer.

As mentioned by the experts above. Many problems start and end with battery in the H3 and also in the remote.

When the ghosts start electrical and fuel are good places to start on mystery.

 

Thank you everyone for your help. I ordered a new master switch for the driver side door, cost $33, took less then 10 minutes to change it out and everything works just fine now.

 

It actually takes less than a minute to change the master switch. Btw, keep the old master switch, I know it still works!
