I have a honda accord 1.8 ls. Just had a new ignition barrel fitted. Since then the deadlock system has not been working either with the key or the remote fob. I know the remote fob is working as when I tune the fob to the car I can hear the locking mechanism clicking....but when you take the key out of the ignition the fob doesn't work....Can anybody help?

I just brought my car in because the AC was working, but not blowing cold. The emergency brake light won't go off. And the automatic door locks won't work (the doors lock manually but not auto). We just got the call that the entire fuse box under the steering wheel needs to be replaced. 270 for the part, 300 for the labor. !?!?!?!? It all just happened over the last weekend! They said not to drive it anywhere because you never know and all the electric could go!!! Not sure what caused it, but it sounds like I'm not the only one...

For the system to arm, the ignition switch must be off and the key removed. Then, the multiplex control unit must receive signals that the doors, hood, and trunk lid are closed and locked. When everything is closed and locked, none of the control unit inputs are grounded.

The door switches, hood switch, trunk lid switch, door lock knob switches, and door lock cylinder switches are all open. Ten seconds after the doors are locked with the key or the lock knob, or immediately after locking the doors with the remote transmitter, the system arms.

If anything is opened or improperly unlocked after the system is armed, the control unit gets a ground signal from that switch, and the system is set off.

If one of the switches is misadjusted or there is a short in the system, the system will not arm. As long as the control unit continues to get a ground signal, it thinks the vehicle is not closed and locked and will not arm.

An alarm that sounds for no apparent reason may have been set off by a switch that is on the threshold of misadjustment. In this case, it may only take a significant change in outside temperature, the vibration of a passing truck, or someone bumping into the vehicle to make the alarm sound.

more than likely you have a bad lock actuator in one of the doors usually the drivers door

I've not heard of Brake Codes working on the 3rd or 4th generation Rolling Code Sidewinder Keys. There is simply no reason to, since a Honda Tech can simply access the Immobilizer System through the HDS (Honda Diagnostic System Laptop) with the Daily Access Security code providec by the Honda System. He can even reflash (reprogram) the ECM using this Daily Code.

In a case like this, normally Honda will have the Accord towed in and do a "All Keys Lost" reset with a new set of keys. This will also prevent your "Lost keys" from being used in the future by who ever may find them.

If you ever buy a used Honda at a Honda Dealership, most likely they also did a complete Key code reset just in case to protect you.

All you need to do is push the Shifter in harder into park and the key will come right out.. I had this problem once too.. The car just doesn't know it's in park because you didn't push it in far enough.
