BMW E46 Key (no coding!!!)

BMW E46 Key replacement with no coding required! This is just a quick edit (and audio kinda sucks), I will have a second video showing a different kind of remote, and some more close-up shots uploaded soon.

[@BobIshidaHere]

Amazing! I've never seen this level of DIY for the key. Thank you for sharing!

[@lukas______]

Just buy a $15 AK90+ coder, plus a new $6 key from AliExpress. Easiest method possible. Make sure the key includes a the circuit board and ID44-7935AA (PCF7935) transponder chip. If you're in the US, you need 315mHz frequency; Europe 433mHz.

[@sergiodelucenareynaldo6627]

it worked perfectly, thank you very much

[@alextheboobalishious]

I was able to follow along but dont trust myself with the soldering, would i be able to cut the corner off the key ? with the cap, coil and transponder? since its already pinned correctly

Good advice BEFORE DISASSEMBLING the key! Faced the problem of a broken key (was in the table for 3 years). I thought - well, that's it, I need to change the battery, I started watching these videos! Before opening the key, order something on Ali, etc. - try the following: 1) charge the idle key! 2) after charging, try to bind it to the car! 1) The battery is very reliable inside. But it also sits down with time. It is charged - while driving - when the key is inserted into the lock. Ride for a couple of hours with the key in the lock! 2) After such a potential charge, try to bind to the car. On many forums and videos - it is written how to do it. (Briefly: Press "Open" - while pressing "Open" - press "Close" 3 times. Then release "Open" - and the doors should close and open.) If this happened, then everything is fine! The key is charged! You just need to charge it sometimes! I did so - and it helped me! I saved myself from the fun activity of sawing a key and other dances with a tambourine. Maybe this advice will help someone else.

Great video.

thank you!

[@IsmailRidi]

Awesome Video man! Just one comment: A heat gun and tweezers would've made your job A WHOLE LOT EASIER :) with removing the components

[@AlecKristi]

agree, but I don't have a heat gun )

[@petergondolier4088]

Any chance you saved or at least measured the capacitance value of the one you removed from the OEM board?

[@hoderalus]

How it looks transponder on new key?

[@mataamafelomale4791]

Which key do you use in the first instance where you turn to position one and hold unlock while pressing lock? Don't you have to do the same pressing on the original key first?

[@AlecKristi]

No, you don't need to press anything on the original key. All you need is a valid chip on the key in the ignition.

[@JohnFaire]

That's awesome. Wish I saw this before I bought the AK90+ coding module. But it was cheap... Question: Reason why I'm here is bc the diamond key often hits the trunk unlock while in my pocket or pulling it out to start the car. Happens enough to where I looking for a better design. I think your key fob would work better for this problem. Have you encountered anything like this with that fob?

[@AlecKristi]

never encountered this issue... the remote I have used is able to be disassembled, so it is ultimately easier to troubleshoot.

Hello. how to program this key on open and lock function? my car e46 2001

[@punchgawd]

How much to do my key?

[@kefalandia]

Hello. Thanks for the video but I have a question. The remote control of my key stopped working and changing the battery didn't help and I don't want to pay much for a new key. I was wondering if I order a key with remote control without a chip and if I unsolder the chip from the old original key and glue it inside the new key is it going to work or not ? Thanks.

[@AlecKristi]

You have to make sure to grab the chip, the capacitor and the coil, and solder them together like I show in the video. The chip by itself has no means to communicate to the lock. The led is only for fun, you don't have to solder it on. If you're uncomfortable soldering, you can program a new key to lock & unlock, and use the old key to start the car...

[@kefalandia]

@@AlecKristi why there is a need of capacitor and coil the new chips on AliExpress don't need them

[@AlecKristi]

@@kefalandia the new chips have the capacitor and coil integrated inside the chip, and they do not have any soldering connections. The BMW chip uses external components because it also charges the battery. The BMW chip cannot communicate without the coil and capacitor.

[@kefalandia]

@@AlecKristi thank you

[@darek4488]

I need to transplant the ELMOS chip from one diamond key to the other. Any tips how to do it? It is so small, I am afraid I will mess it up. I only have a soldering iron. Should I buy something to make it easier?

[@AlecKristi]

some good flux and a desoldering braid will do magic. I recommend using a temperature controlled soldering iron to avoid messing up the components.

[@darek4488]

@@AlecKristi It was 7 months ago. I have bought a hot-air soldering station and managed to transplant the EWS chip from my old key to the new remote.

[@AlecKristi]

@@darek4488 glad to hear that. For some reason I got heaps of comment modifications just right now, for most of the comments from last year or so...

It's a TS-100.. It's old now, there are better versions of it available.

[@emreakuzum4752]

Hi i got that flip key f series style but it wont open and close my windows with remotebutton. The car is coded and the other keys work any advice?

[@AlecKristi]

Have not ran in to that issue before... Maybe the particular key you have doesn't support long press?

[@emreakuzum4752]

@@AlecKristi do you know a way to fix it modifying the fob

[@AlecKristi]

@@emreakuzum4752 I'd try a different key fob, or a different internal circuit.. they're very cheap.

@@emreakuzum4752 I wouldn't know what to recommend at this point, as haven't purchased any since before the video.. I'd probably just be googling..

Hey, nice video. I tried the same, unsoldered and moved with wires. the remote works but the car does not start. maybe wrong wires. I got them from an old USB cable. I can send a photo if needed. mvg, Ronny

Hey I was trying to have u make me this same thing for me with my key I ran it over on accident and its not working anymore. I have a 2001 BMW 325i. If you could reach back out to me that would be great.

[@brendenns3926]

Please help: do i really need the coil of wire thing aswell, if i dont want an led, just the transponder chip at the very front of my key would that still start the car? (I take it the coil is only to receive power for charging the battery)

[@AlecKristi]

The coil is actually used to communicate to the lock and to power the transponder chip. It's basically the antenna for the chip. You need both the coil and the capacitor for it to work, as this chip isn't like the chips in the cheap transponder keys that have the coil built in...
