Contactless locking/unlocking (coding)

[iambak]

Hi everyone,

I wanted to share a piece of code that allows you to unlock and lock your car based on proximity. I've tested it, and it's working perfectly. However, I didn't add it to the cheat sheet because I used Esys for the coding and haven't tested it with BimmerCode because i don't one one.

for reference i have 2023 MT

Head Unit (HU_NBT2)

• 3000 HMI - CKT_DOOR_LOCK_UNLOCK - aktiv
  • This enables the option in your head unit under the key options menu.

Body Domain Controller (BDC_BODY3)

• 3030 KeyManager - CKT_ENABLE - aktiv
  • Activates the proximity unlock/lock functionality.
• 3030 KeyManager - CKT_FUNCTIONS - light_unlock_lock_preauth
  • Enables the specific functionality for proximity-based unlocking and locking.

Once these settings are enabled, you will need to select the appropriate options in the menu to activate the feature.

i'll add some screenshots when i get a chance

Feel free to try it out and let me know your results!

Edit:
Attaching this PDF I found around how the comfort access works

Ohhhh snap, gonna try this tonight

Just tried it and it works like a charm! Triggers when you're about 10 ft from the car. It's crazy how many features they hide from us. Thanks!

I’m surprised there hasn’t been a leaked tech manual that has all the options. Info has to be somewhere other than a guarded hidden underground vault in bimmerland.

Maybe I’m an old fart but this just screams “make it easier to steal my car!”

I mean, maybe?

Scenarios:

- Theif already has the key, and is treated to a proximity unlock
- Theif is waiting for you to slap the unlock button
- Theif is waiting for you to get in the car

It SEEMS to me like most of these the proximity unlock doesn't solve.

You can just enable the auto lock and not the unlock if you're worried about it.

This won’t change anything. The best car thieves use a relay which basically just emulates your keyfob, so this won’t change anything unless somehow you mistakenly unlocked it and didn’t code in the portion to have it auto lock.

It would be awesome to know if this could be done in bimmercode expert as i dont have access to esys

Well shit, I guess I am just an old fart. ?

Just did it on my car with Bimmer code. Works perfectly!

@iambak thanks for finding this! Seriously awesome find.

Added it to the list:

So, the million dollar question: Is there an option to include the trunk? That would be awesome, if it would unlock, as you approach the car. I wouldn't care if I didn't need to access it every time, for I would just tap it closed, before getting in the car.

Also ran this via bimmercode and it works! One of the huge things missing from this car that my M340 had! Thanks all!

It's gonna take me a while to get used to just walking away from my car and trusting its going to lock. It's such an odd feeling. I'm so used to touching the 3 lines on the door handle.
