Attached Images. Second Lieutenant. Since we ordered our cars before this option is available.

Will we be able to add this feature in the future??? I am getting comfort access when I get my new car. I would most likely keep it in my pocket or sachel. So, if I just walk by my car it unlocks? Let's say my car is in the driveway and I just walk by it to the neighbor's house. Now my car is unlocked? Now I have to worry about did I just walk too close to my car? Is is locked or not? How do you let passengers in?

Does it unlock their doors too? What about carjackers? And if you don't have it, now you have to insert key and press button? That is weak. I might like it if they didn't unlock until you pull the handle. Just another example of fixing something that ain't broke! When replacing your BMW remote key fob , knowing whether your vehicle has Comfort Access can help you understand the steps required to get your new key working.

Depending on your BMW's model, you may be required to purchase a special Comfort Access-compatible key or have your vehicle coded to activate your new fob. This all adds to the cost. These vehicles also put a limit on the number of keys that can be paired with the car at any one time, meaning BMW Comfort Access programming is required to delete your previous fob from your vehicle's memory before activating your new one.

When ordering from BimmerTech, we are able to send the correct key type for no additional cost, and there is no need to code your vehicle during activation. Well, BMW doesn't really give you the option to deactivate Comfort Access — not without having a third party make substantial modifications to your vehicle, at least. The most common reservation people have about Comfort Access is around security. Smart key systems from all car manufacturers have been blamed for facilitating theft, letting criminals access your car without needing immediate physical access to your key.

To understand how it all works, it's necessary to understand how Comfort Access works. Basically, your BMW remote key fob broadcasts a low-power signal with an identification key, which can be read by your vehicle from up to 5ft away. If your BMW reads a fob broadcasting a valid identification key, the doors can be unlocked.

To improve security, the identification key broadcast changes regularly in a way that is unpredictable without understanding the underlying encryption, making it effectively impossible to crack the system. However, if a criminal can get close enough to your key to be within the 5ft range of the signal — for example, if you keep your fob near your front door — they may be able to use a signal amplification device to broadcast the identification key from your fob much further than the safe 5ft, potentially making it possible to unlock a vehicle parked on your driveway.

The security built into Comfort Access is powerless to prevent this kind of abuse. Some manufacturers, including BMW, have begun designing keys that shut off when left motionless, meaning a fob left on the side overnight won't be a security risk. Third-party companies also offer Faraday cases for fobs that block the signal, which can be left on permanently or only used as storage. With no signal coming from the fob, thieves won't be able to exploit your Comfort Access system, making it as safe and secure as a traditional key.
