Getting a new set of keys for your BMW used to be pretty simple. Just take your key to the watch / jewelry / shoe / etc. repair guy down the street who also happened to offer while-you-wait key cutting, and get a whole bunch made.
Modern remote keys have plenty of security benefits and make it easy to get into your car and hit the road — particularly if your BMW or MINI has the Comfort Access feature. But for all this convenience, they can be a real pain to get copies of.
Maybe you want a spare in case you lose your primary key, or perhaps you share your BMW with a few family members and want everybody to have a key of their own. Maybe your existing key is just damaged, and you need something fresh.
Whatever your situation, BimmerTech makes it easy to get a new genuine remote key for your BMW or MINI.
Before shelling out on a new remote key fob, it's worth making sure your existing one really needs replacing. If it's not working, it could just be that the battery has run out.
If you've got a key fob that you have to insert in a slot behind your BMW's steering wheel, you might be able to skip this step. Many of these fobs have rechargeable batteries designed to be topped up automatically during use; as soon as it's put in the ignition slot, it starts charging.
If you've got Comfort Access, though, your key fob will likely have a single-use CR 2450 battery, which will need replacing periodically. It's a simple DIY job that only requires popping off your fob's rear panel and switching out the coin cell battery.
Depending on your vehicle and usage, a battery should last anywhere from one to three years before needing to be replaced.
If you've tried replacing the battery and your key fob still isn't working, or if you've lost your fob entirely, it's time to get a new one. BimmerTech is able to offer replacement keys for almost all BMWs and BMW-produced MINIs from the last few decades.
All our keys and key fobs are BMW/MINI originals, and will look exactly like what you got from the factory. They'll also come pre-programmed for your specific vehicle, to ensure complete compatibility.
You won't have to worry about trying to get to grips with your vehicle's immobilizer, EWS or CAS system. Just pick the appropriate key for your vehicle series — either E Series BMW, F/G Series BMW or MINI — and we'll do the rest, based on your VIN. We can even offer multifunctional touchscreen key fobs for the latest G Series BMWs, either to replace your existing key fob or to add this feature to your car.
As standard, our keys do not include the internal key blade — the traditional key that slides out of the base of the fob — which can easily be switched over from your existing key fob. If you're looking for a spare rather than a replacement, you're going to need an internal key blade, which can be added when you order. Without it, you'll likely be unable to access your vehicle next time your fob's battery runs flat.
Your key will come pre-programmed for your vehicle, but will still need to be activated before use.
To do so, hold your new key fob flat against the low key battery indicator on the side of the steering column. Then hold the start/stop button until the 'no key' warning light disappears. Press the start/stop button again to confirm activation was successful.
If this doesn't work, you may need to take your existing key fob out of signal range when activating your new key, to prevent interference. To do this, unlock your BMW with the existing key, then have somebody take it a reasonable distance from your vehicle. You can then place your new key against the steering column and press the start/stop button.
To activate your new remote key in MINIs produced since July 2004, there's a simple process.
With all the doors closed, turn the ignition switch to KL-R (the first position), switch off within five seconds and remove the key.
Within 30 seconds, press and hold the unlock button, then whilst holding it, press the lock button three times within 10 seconds.
Then release both buttons and turn the ignition to KL-R to complete the initialization.
In E Series BMWs and MINIs with the Comfort Access feature, key fobs activated as described above will only unlock your vehicle when used manually, and cannot be used with the Comfort Access feature.
To activate your new key fob for use with Comfort Access, it is necessary to code your vehicle to delete the existing key profile and set the new key for use with Comfort Access. This can be done at your local BMW/MINI dealership, or we are able to code this for you remotely.
Our touchscreen key fobs for G Series BMWs also require coding, which is included in the price. Contact us for more information.
The above activation methods assume you have a new key fob ordered from an authorized BMW dealer or third-party reseller, such as BimmerTech, which was made specifically for your vehicle based on its VIN. These methods will not work with a used key fob, or one intended for use with another vehicle. The majority of key fobs available for sale through online marketplaces such as eBay fall into this category.
To improve vehicle security, your BMW's head unit will only allow activating fobs with one of a predefined list of identifying keys. This list of approved fobs is unique to each vehicle, preventing criminals from pairing other key fobs with your vehicle to gain illegitimate access to it. Reprogramming your vehicle or a used key fob to allow the two to be paired would require overriding key parts of your BMW's anti-theft system, potentially compromising its security.
Like BMW, we recommend only attempting to use key fobs ordered from a BMW dealership or a reputable third-party reseller, such as BimmerTech.
As a security precaution, all customers are required to submit evidence of vehicle ownership before we can provide a new key or key fob. To do so, please email a copy of your vehicle registration document and driver's license with the same name to [email protected] after you have placed your order.
A new BMW key fob isn't just a good idea when you've got a lost key fob; it can also be worth adding an extra fob to your collection if your family members share your car. Getting a new fob is also a good opportunity to take another look at a few of the BMW key fob features you might have missed, particularly if you're buying for a used car.
If you share your BMW with colleagues or family members, chances are you won't all have the same preferences behind the wheel. Adjusting the steering wheel and seat position every time somebody new gets in the car can be a hassle, but its one that an extra key fob can solve.
Each BMW key fob can be associated with a different driver profile, which includes saved presets. Unlock your vehicle with the key fob associated with a specific driver profile and the seat will automatically slide into your preferred position. When another driver unlocks the car, the seat will slide back to a previous position.
Besides just locking and unlock your BMW, your BMW can also perform additional functions remotely, including controlling the windows and sunroof or folding the wing mirrors. Window control is ideal on hot days when you want to want to air out you car, or for ensuring your car's windows are all shut firmly when locking your car. Automatically folding in your wing mirrors when locking your car also helps reduce the risk of damage from passing vehicles.
Both features only require pressing and holding the lock/unlock button on your remote fob. Availability of this feature may vary depending on your vehicle and country, but can be activated in a remote coding session with a skilled BimmerTech technician. Doing so adds an extra layer of convenience to your new remote key fob.
