DIY: Disable the Door Open chime.
(Copied from the Australian Forum, but this should work on any 8, I think.....!)
The chime is fitted to the RX-8 as a reminder to remove your key when you open the drivers door with the key in the ignition, it's also known as the key reminder chime. I like to occasionally run the stereo with the drivers door open...unfortunately the key needs to be in the ignition to power the stereo, and the result is unpleasant to the ear!
Okay, I could remove the instrument cluster and kill the chime.....but then the redline beeper and headlight on warning would not work. Turned out there was an easier way, anyway. Disabling the door open switch on the rear door would kill the interior (and exterior mirror ground illumination) lights, and I wanted to keep them functional.
There is a two wire connector on the ignition switch that sends a signal to the keyless control module when a key is inserted. I disconnected this and tied it back to prevent any annoying rattles.
Disconnecting this connector does a few things.....it stops the door open chime (hooray), it prevents the interior light and exterior mirror lights coming on when the key is removed from the ignition (this still happens when a door is opened, so no big deal), and removes the signal that disables the central locking remote ....ie you can now lock the doors (and open the trunk) with the fob remote while the key is in the ignition (Edit: With restrictions.....my car only enabled the fob in Acc or Lock, others have reported fob also works in "On" .....). If you have an alarm installed, it may affect its arming in some way, too.
Pics attached......

There is a lower steering column cover that just clips out to allow easy access. The shroud over the ignition switch is easily removed with 3 screws to be undone from beneath.....here you see I have left the lower half of the shroud dangling by the key illumination wiring.....make sure you disconnect and tie back the connector with the blue and pink wires! You can see it dangling down here and in the above picture.......Reassemble, and you're done!

All too easy.........now I tried to get the stereo to run without the key by shorting out the accessory relay contacts with the relay removed. This worked, but the clock was permanently illuminated, even with the stereo off and key out. Doing this also permanently powered the cigarette lighter and accessory socket....no bad thing IMO. If I can suss out a way to remove the backlighting power from the clock/info display, I'll be home and hosed!
The relay is this one where the tip of the key is....

If you're a bit of a contortionist you can get to the connector without taking the steering column shroud off....may be a little hard to tie it back though......

Following two posts from another thread https://www.rx8club.com/showthread.p...334#post405334
Hi Gomez,
Am I understanding correctly that when you said
it means after this mod the car cannot be locked by pressing the driver's side door lock switch even with no key in the ignition?

That's correct...you either need to put the key in the door to lock it, or use the fob.
The chime is there to remind you to remove your key when you open the door.....if you always use the fob to lock the car, the chime is redundant.
Try it yourself, remove the connector, takes 15 minutes to do.....

Hi Gomez,
Thanks for all the info. You may want to add to the list in your first post of this thread that the drivers-side door switch cannot be used to lock the car.
I'm in the habit of locking my car with the door switch. I was interested in understanding the full effects of disconnecting the "ignition key reminder" connector - and it's all clear now thanks to your help
.
cheers,

May I ask if there is a reason you use the door switch? I find the fob to be much more convenient....and the transmitter works for miles....well I can open my car from over 400 ft away! It has locked itself by the time I get to the car, but that's not the point!
Impress your friends...... damn the cost of the little batteries!!!!

You mentioned that expensive little battery - I'm using mine 50% less than you :D.

I tried this on my US spec 8 and you most definally can lock the keys in the car. I did it intentionally having the key in ACC and hit the drivers door lock...both doors locked and did not auto-unlock. Then I shut the door locked...it stayed locked. Tried it with the key in the ON position and did the same. Looked like all the other information given above reguarding the disconnect is accurate.
Not sure if this is only US spec cars or not, but wanted to let you all know.

Interesting.......our cars are different in a lot of ways, but I'm surprised to discover that the locks would work differently. XcelR8, does your car have an alarm or some non standard mod?

Yes, after the mod the doors would lock with key in.
No aftermarket alarm system.
I left the mod done and will just be careful when the keys are in the car. I normally use the key fob to lock the doors anyway.

Okay, next question is.......Do the U.S cars allow you to lock the doors with the key in the ignition (in Off, Lock or On) when the car hasn't had the mod done?
Gomez.
Edit....wind the window down before you try this!!!

Caution ......... long reply:
My car does not have the mod.
If I have the key in the ignition, as long as all the doors are closed, I can hit either the door-lock switch or door-lock ***** and lock both doors - but I'd have to be sitting in the car or have the windows down to do this. I don't think you care about that scenario, but I'm throwing it in to be complete.
If I open the driver's side door, then try to lock it by pressing either the door-lock switch or door-lock ****, both ***** pop open as expected, because the car is preventing me (the driver) from trying to lock the car while the key in the ignition.
Now, key in ignition, doors locked, I'm sitting in the driver's seat and I reached over and flipped the passenger door-lock **** to unlocked, opened the passenger door, flipped the passenger door-lock **** to locked, closed the door .......... and with my key sitting in the ignition all doors now locked!!!! (Wow, this is a new trick I learned thru this experiment). This simulates dropping a passenger off and shows that they can lock their side before closing their door so the driver does not have to lock the passenger door.
I tried it again from passenger seat and was able to lock my key in the car while it was in the ignition. I had to use my second key to unlock the car.
If I opened the passenger door, then hit the door-lock switch on the passenger side, both ***** popped to unlocked, preventing the car from being locked with key in ignition.
Another way I have locked the car while the key is in the ignition is using a second key in the driver's side door.
In summary, I can only lock the key in the ignition two ways: using the passenger's side door-lock **** (not switch) or using a second key in the driver's side door.

PS: XcelR8's post saying key could be locked in the ignition puzzles me too! I'd expect that the disconnected "key in ignition" switch connector would make the system think the key was always in the ignition if the chime never goes off. So I'd expect the car to definitely prevent door locking if the key is in the ignition and the driver's door-lock switch is pressed while the door is opened.

Thank's for your investigation.....I'd say my car still works the same way. When I get a break I'll reconnect the connector and check out what my car does with regards to locking with the door switches......

If the car cannot see the "key in ignition" signal, then it makes sense that one could now lock the car with the keys in the ignition. Argh! - this was my original concern
![Smilie](https://www.rx8club.com/images/smilies/smile.gif)
It will be interesting to see what results you come up with when you do your un-mod'd test.
If I ever have reason to get near that connector, I'll repeat my experiment, but I don't envision that happening any day soon.

Okay, reconnected today and checked the behavior of an Australian 8, re: the door lock switches. Nothing had changed. I could not lock the drivers door with the door open (R/H door). Pushing the door switch resulted with it popping out again, regardless of ignition switch position or even with key out. This R/H door operation is the same as reported by rx8cited previously.
The key reminder chime is handy in LHD models if you yourself are conditioned to push the switch and hold the handle up while closing the door, as rx8cited does. The chime would remind you to pull out the key before you lock the door. Owners of RHD cars, I've discovered, cannot lock the keys in the ignition when exiting from the drivers side. The door wont lock.
It seems that Mazda has designed the car for a RHD market and added the key chime to prevent LHD owners from locking their keys inside. The door locks behave the same LHD or RHD, it's just that LHD owners are getting out of the passenger door when they pull up!!
In summary, doing this mod will not change the behaviour of the door switch or door lock operation, but it will kill the key reminder chime. If you are in a LHD car and are in the habit of holding the handle up and locking the drivers door when you exit the car, BE WARY.!!
I've had a response from a Canadian forum member who is rapt with this mod. He can now lock the car with the engine running while he goes to the shops for a minute or two.....he lives in a small town (no thieves!). Normally, pre-mod, the fob is disabled with a key in the ignition. Post-mod, he leaves the engine running, fobs the car locked, and races in to collect his mail from the Post Office. Prevents flooding if the car has only been running a few minutes before getting out...........
I can't do this on my car, the fob I have will only work when the key is in Lock or Acc.....
There you go, I hadn't realised one simple mod could be beneficial in this many ways!
Gomez.
P.S......Now I know exactly where the connector is, I can remove/install it without any disassembly at all......on a RHD car...........

In my test, I did not bother to describe all scenarios without the key in the ignition.
If the key is not in the ignition , I can lock either door with the fob, either door-lock switch, and either door-lock **** regardless of either door open or closed.
You said:

I'm not sure which handle your describing holding up in the following?:
