If Honda never offers a solution to fix this someone mentioned the following to me on how to get the auto door unlock to work on all the doors:


"You can probably fix this for under $10. You can use a DEI 452T module to add ignition controlled locks. You could use the factory 9mph to lock the doors and then use the DEI 452T to unlock all doors when you turn off the ignition. It takes about 15 minutes to install... any stereo installer can do it. Very simple."

OK, I'm going to borrow quite a bit of information from Vinny over at the MDX site. I've made this change on my MDX. The MDX, Pilot, and Ridgeline are all very similar vehicles. I believe many of the wires and locations will be the same, but since I don't have a Ridgeline to look at I can't tell you if things are exactly the same or not.

This conversion is based upon the DEI 452T Door Lock Pulse Generator. It's available in many locations, but here's one I know of (cost $7.99):

Here are the instructions for the module:
http://www.azcartoys.com/images/425T.PDF (note that you won't use most of the wires!)

Since I understand that the Ridgeline has the option to autolock all doors at 9MPH we don't need the 452T to do any locking of the doors. I'm told the Ridgeline will only unlock the drivers side door via the factory settings. We can fix that with the 452T. If connected as described you will unlock ALL doors when the ignition key is turned off.

The doorlock wires are behind the passenger side kick panel on the MDX... probably the same on the Ridgeline:

The power lock wire is black/orange and the unlock wire is blue/orange. You only want to unlock so only hook up the blue/orange.

Use the fuse box below for constant 12v and igition 12v. There is a bolt below the fusebox for ground. NOTE: Picture is not correct for Ridgeline install and module now looks different (much smaller). Must be true ignition 12v and not the delayed power that stays on until you open the door.

There's plenty of room behind the panel to keep the module and all wires hidden. NOTE that the actual wiring for the Ridgeline is not represented here, but the concept is the same.

The MDX and most likely the Ridgeline has negative pulse locks so other than power only the solid blue wire is used.

The entire procedure is very simple and probably not as complex as I've made it seem here!

Thanks for the details csimo, much apprecaited. Defintely will do this if Honda doesn't offer a solution soon. Soon as the Service Manual comes in the mail I'll check out the wiring diagram and add more details.

Does anyone know where this module would connect/mount in the Ridgeline? I took some co-workers to lunch today for the first time and wound up leaving them stuck in the damn truck!

The funny part is that my former car had auto unlock and one balky door lock that would occasionally fail, stranding the right rear passenger in the car. My friends are quite impressed that my brand new truck has exactly the same feature!

WOW! I can't believe there are people out there that still tap there wires into the fusebox at the fuses. Talk about NOT SAFE. I hope you independantly fused each of those wires after their connection at the fuse box, just in case the module ever fails.(I only see 1 fuse) It is always good practice to spend the few extra minutes to run wires directly to the ignition harness. Just a word of advice from a MECP installer/shop owner.

I like the info on the lock module, but I did notice also you tapped into the fuse. Thats a no no in my book. Once the RL repair manual is out I am going to directly wire all my doors to unlock with the drivers door. I have done this on several other cars when I worked in a shop.I see no reason for it not to work on the RL.
