Tied to the console lock button, it will not unlock the doors.

If I was to do it, I would put a switch inside the trunk and you would need to wire in to the keyfob receiver output.

This would solve all but locking your keys in the trunk.

I GIVE UP! The only way around this is to spend money!!!

Last night I just went to BMW Of Westchester down the road from where I live and bought a New Master Key is $165 ($178 with taxes).
to replace my shredded one that I use. As you see the old shredded up Master key below will get replaced by the new key.





I also ordered a new lock cylinder repair kit ($32 shipped) off eBay



...AND I sent my second Master Key, which has a dead battery but looks brand new, to this guy to have him replace the battery ($49) So that this key fob will open the car and allow me to open the door to fix the lock sylinder and then drive it to BMW Of Westcheter so they can code the new Master key. (They need to get in the car to code the new key before the new key can work).



I had also ordered a battery for the old shredded up Master key....



but it seems that my older Master key fob is going to be destroyed for good when I finally get it opened to change the battery




so I want to order this to transfer the remote chip into and keep as a third back up Master Key Fob that would only have the remote lock/unlock chip but no key blade to start the ignition.

I repaired my lock cylinder, but then my son was locked out (of course our fobs are long since dead). When I took the cylinder out, it turned freely, but didn't appear broken. However when I pushed in, gently, it turned left and worked. I did it over and over. I am wondering if the replacement spring is the culprit? Perhaps it doesn't have enough tension in it to allow the mechanism to work. Has anyone else had this issue? Again, it's not broken, just not reliably turning.

I tried that and it doesn't work. There is absolutely no connection to the key chamber and the tumbler. That is why the key spins freely. No connection is being made.

The dealership service department told me that these cars are NOT designed to be continuously locked and unlocked with the key in the key hole. Overtime the tumbler components WILL wear out and break down. They also scolded me in saying that is why we are supposed to spend hundreds of dollars replacing our master keys immediately when the battery dies because sooner than later your tumbler goes and your remote is already dead and your key just spins and you are locked out.

The tumbler kit is $30 on ebay and takes less than 10 minutes and a simple allen wrench to replace.

However, The BMW Dealership Service Dept. will have you replace $500 in parts with new keys ($200+) and labour ($200+).

Most local shops who are keen on making easy coin seem to charge $100 to $300 to fix it.

But I'm sure they all go on eBay and spend $30 on the same part and take 10 or less minute to replace the tumbler but they bill you for hours of labour and hundreds of dollars for parts!

shame shame shame!

The ebay parts are the only way to go, otherwise you have to purchase the engine lock cylinder from the dealer that will likely be $150 or more??

The link is designed weak and to break to help reduce theft.

Yeah this is what the Service guy said.

Designing a weak tumbler that is fairly cheap and easy to replace (versus replacing components lost from a break in) kind of makes sense.

When I do the write up for this project I will be sure to mention when your key fob battery dies be sure to change the battery as soon as you can ($40 for the eBay mail in your key repair service) or buy a new key ($200) because sooner than later your lock tumbler will go next and you will be locked out of the car (for those without fold down seats) and have to replace the tumbler and the keys and possibly have a tow truck bill.

I bought a $65 "plastic key" for a back up. Glued it to the under side of the car only so I can find it. This should help if I ever get locked out.

It is not that sort of locked out. It is the lock out situation where the door's key hole tumbler is busted so the key just spins without connecting to the locking/unlocking pin.

I tried the repair kit and it wasn't reliable. It initially worked, but I think the spring just didn't work. So I ordered a complete lock cylinder from my BMW dealer. It cost $122, but I get a 10% military discount and it ended up being a little less.

Installing the door cylinder is easy. I also bought a new key. Not cheap at $145, but quick and easy. It works.

My kit's spring did not match the spring that came out the original tumbler. And when I used the new spring the fitment was off and the tumbler got stuck the minute I turned the key.

The only way to get it unstuck (where I got the key free) was to break the locking plates I just replaced.

I had to reorder a new kit but I think when I attempt the repair again I will just reuse the original spring.

Here is a video showing how far I got and how different the kit spring :

I just figured I'd spring for the $120 and have a warranty.

Yeah I may end up doing that. so dar I'm $64 deep ($32 x 2 kits) and my lock ain't fixed yet.

Thanks for that heads up. If the second kit don't come thru then I may head back to the dealership or buy on of those sets off eBay.

Here's the process for removing it.
Works if the door is already open... For those of us locked out, not so well.

You could possibly try to carefully cut your current key open and replace the battery and HOPE the keyfob works to unlock your car door.

You have to be VERY careful not to cut yourself or the EWS components on the keys circuit board.

You really need to order another key anyway, $160 for a new keyfob from the dealer is typically a good price. Shop around if they want more.

With the replacement keyfob, if you screw up the EWS circuit on the old key you will be able to start the car with the new key once you get in the car.

I have not confirmed this will work, but search Car Kracker on the forum here, it appears if you had a Car Kracker module and you could tie into the Ibus in the trunk, you might be able to use a computer to open the car doors??

The problem is the Car Kracker circuitry, the software, the computer and will it really work?? It should, but I have not confirmed this.

In order to unlock the doors with the interior handles, you need to push the central lock button first. Sounds like you are SOL as your central lock button is broken also.

This is a CLASSIC case that we are seeing over and over again of 2nd to 5th owners with one key and the keyfob does not work and/or the drivers door lock linkage is broken and/or the only key is lost or locked in the trunk.

EVERY E46 OWNER NEEDS 2 WORKING KEYFOB AND A WORKING DRIVER DOOR LOCK!! The $200 you spend now will save you plenty more money and time in the future. BUY ANOTHER KEYFOB AND MAKE SURE YOUR DRIVERS DOOR LOCK WORKS NOW!!

http://forum.e46fanatics.com/showthr...484&highlight=

Good luck. Hopefully it will not be hammer or brick time??
Apparently that is exactly what time it is when 3 failsafe systems fail. and that is according to a friend who is an engineer at BMW.

A) keyfob battery dies.

Failsafes:
#1) back-up key gone.
#2) manual entry fails due to lock cylinder failure
#3) break-in method of pushing center console button, double pull on door handle fails due to broken bottom on console switch...

= Brick through cheapest window. which is the big window behind the driver.
Not the small one, it's glued in and costs more in labor to fix.

Maybe make a sticky of that highlighted bit for those of us who didn't want to buy one of those damned expensive fobs.

Found the solution, just before I used the brick!

Sharp blade, soldering iron, common battery(#2016) and 30 minutes.

Dan, goes by the moniker Sir-fixa-lot, on YouTube... .

Wahoo! I have been saved
Hope this saves another wretch like me.

I'm sorry to bring this up from the dead, but if you were to hold the key in the unlock position would it roll the windows down despite being disconnected to the rod inside the door?

Yes, ASSUMING the keyfob works and the car is coded/programmed to roll down the windows with the keyfob. However, in many cases where where get to the situation where this thread comes up the keyfob has not worked for a while and the owner is using the key in the drivers door lock when the door lock linkage breaks because it is designed weak to help reduce breaking into the vehicle easily.

I'm aware of what happened. My fobs battery died and I'm currently using the key lock on the door and I am basically on borrowed time with it. However, with my car, if I turn and hold the key in the unlock position, it will roll the windows down, despite my key fob battery being dead.

If the lock breaks, but I can still turn the key, if I turn and hold it in unlock, would it roll the windows down?
