Best diy since cdv delete! E46 key swap to e90

Its finally time for me to contribute to the fanatics. Heres a quick diy that i came up with all by myself (and it definitely deserves a gold star)
How to swap your p.o.s. e46 diamond key into a super sweet e90 flip key.

Step 1. Buy a e90 key from ebay, i bought mine for $20 w shipping.
Step 2. Cut your diamond keys seam so you can take out the rfid chip.
Step 3. Take the brushed cover off the e90 key and remove the four screws then open it up. There will be two plastic prongs in the middle and you need to cut them off so the shell is somewhat flush.
Take your diamond keys rfid chip and lay it inside the new shell. The plastic prongs on the side should line it up perfectly for the buttons to be pushed. The only thing is the case is a little too deep for the chip so i used the foam that was supplied with the new key to keep the chip firmly in place.
Step 4. Put the key case back together and remember to wind up the spring beneath the flip key (very obvious how to do this) and test it on your car. Mine worked first try. Just make sure to ground your body before handling the chip by touching bare metal and try not to touch anything but the green plastic on the chip. If all is good, your ready to get your key cut ( i havent done that yet but i dont foresee any issues)
And voila! You now have the second best key possible (second only to mine, the first known key swap)
Sorry i didnt take any pictures of the internals yet, i thought about doing this diy after i got done, plus im doing this from my phone so excuse any issues like spelling please.
If you guys are interested, i can go into more detail but this is a easy project so you probably wont need much more.
Please leave a comment if you liked or appreciated this diy and as always, donations and business propisitions are appreciated.
Enjoy your new key

Frankly i dont think there was a charging unit in either key because there was no connection to the battery which is weird bc in my manual it stated that its important to charge both keys on a regular basis.. so i call bs on bmw for that one. Ive never seen a e46 key thats charged via the ignition. Tisk tisk

All the diamond keys are recharged while the engine is running.
Have seen people retrofitting a non re-chargeable battery.

However, a very nice DIY. Lets see it in detail, the battery is completely gone in one of my keys, so might as well swap the internals to e90 key when I cut it open to replace the battery.

TRJ- i dont think all the keys are rechargeable. There is no way either of the two diamond keys i have can do that. The battery and rfid are completely sealed off from the outside world, so unless the charge wirelesly, its not possible. Not for these keys atleast.

Also, to the person who says flip keys suck, i ask, why? Did you have one break on you ? Bc this flip key is superior to my diamond in every way.

wow stupidity at a new low, have you ever heard of inductive charging

yes our cars are 10 years old but this technology has been around for a long time.

"Inductive charging uses an electromagnetic field to transfer energy between two objects. This is usually done with a charging station. Energy is sent through inductive coupling to an electrical device, which then can use that energy to charge batteries.

Because there is a small gap between the two coils employed in each of the sender and receiver of the energy within the respective devices, inductive charging is considered a short-distance "wireless" energy transfer" - wikipedia

So yes, WIRELESS CHARGING


that is the coil that the electro magnetism induces a charge from

and IMHO your "new' key looks POS

Thx jaryd, i may jave misphrased what i meant although thats no ground for insulting people. Im just trying to share something that made me happy, no need for bashing, unless you were beaten as a child for making your parents divorce, in which case, there IS a need. So i understand where your coming from and want you to know, its ok.
Thanks for the pic and the plagiarism.

Im sorry i was just giving my honest opinion and stating what the manual graphically defines. Growing up in a tight knit family who all live in the same street really gave me a wide view of the world which has bettered by positive upbringing.

Bringing up this assumption of a detrimental upbringing out of the blue on an automotive dedicated forum really does cause me wonder what influenced this completely off topic response whether it was an anecdotal reference i am truly sorry for me assessing this or a drastic conjecture of insecureness.

In all honesty i think that this is far off topic and would much prefer this post to return back to the main focus of the forum, that being the e46 bmw

p.s there is not plagiarism hence the wikipedia reference to the quoted material

Cool idea, but any E9x key I've seen doesn't have a flip...the whole key just sits
in the slot, and the start button is pressed.

Thanks for clearing up the charging part jarryd. So it means the battery will charge if I put the cuts in the other key box, isn't it?
Will have to think whether to do go with this or new diamond key box.
My spare key looks like it has been chewed on, that is the reason I wanted to change the housing on it when I change the battery.

Is this an April Fools joke?







What you got there doesn't look like any E90 key I've ever seen!?

This is an E90 key!






Do you have better pictures of the finished product in-car?

I have an E90, and the key looks nothing like that. It isn't flip, its a fob that is inserted into a slot below the starter button.

This looks soooo cheap! Good that you did it, but definitely not an E90 key.
