How to Program a BMW Replacement Key Fob

If you own a BMW, you likely have an ignition key that opens your doors and then starts the engine. These advanced key fobs run on an internal battery that will wear out over time and eventually need to be replaced.

It's simple to replace the BMW key fob or to program it to your vehicle. Follow these easy steps to ensure that you complete the task correctly.

Battery Replacement

A new battery could be required if the bmw replacement key fob fails to function or becomes less responsive. It's a simple fix and get your remote entry system back to normal!

Most modern car remote keys utilize CR2032 or CR2450 3-Volt battery. You can find out what kind of battery it is from the owner's guide or searching for it online.

In some instances it is possible to find a replacement battery in the local auto parts store or big-box retailersuch as AutoZone or Best Buy. Typically, these batteries cost $10 or less, which means it's worth purchasing one if you require an upgrade.

A dead battery could be a sign of weak signal. If your key fob isn't functioning, you may not be locked or unlocked in your vehicle. This can be an indication of a dead battery but it could also be a sign of weak signal strength which will reduce the range that your key fob will be able to send the signal.

A damaged key fob will also require reset to operate even if you've changed the battery. This will require the vehicle to be reset, and a certified technician will assist you in this process.

Certain BMW cars also have the feature known as Comfort Access that allows the driver to save a preset steering wheel or seat position when locking the car. This is particularly helpful when you have more than one person who has different preferences.

For these features to work, you'll need two or more key fobs with the same driver profile. This is a problem when you share your vehicle with family members.

This issue can be solved by purchasing a replacement key fob from your local BMW dealer, or online at an authentic site such as Bimmernav and BimmerTech.

If you're unsure whether your key fob requires a replacement, contact your dealership and ask for them to look it up for you. They'll inform you if your key fob is in need of being replaced and the likelihood of it being simple.

It's important to keep in mind that a key fob with a rechargeable battery requires charging after each excursion, so it's a good idea to allow plenty of time to recharge the device prior to going on a long trip. This will ensure your key is fully charged before you use it.

Replacement Fob Blade

In the 1990s, key fobs became popular as easy keyless entry systems that allowed drivers unlock their car and then begin it by pressing just a single button. They can also be used to deter theft by making it difficult for someone else to take your vehicle while you're out and about.

Generally, these devices have two main components they have: a battery which powers the system and a key blade, which can be used to open the car's door. The battery, which typically lasts a few years, can be replaced at any hardware retailer or big-box store, and most automakers include instructions in the owner's manual for replacing it.

If your key fob goes missing or damaged, you will need the replacement. A locksmith can usually cut a new key for you. You may also need to pay programming fees which could be costly and not available at all dealerships.

Most modern key fobs feature an integrated security chip or transponder, that emits signals when the ignition is turned off. Certain models come with a switchblade style key that fits inside the ignition, while other models are more akin to traditional keys made of metal with a remote that can be kept in your pocket or purse.

These types of keys can be used in vehicles with keyless entry or Comfort Access. However, some E-series models with comfort access demand that you first deactivate your previous key before you are able to use your new one. If you have any questions you're not sure about, be sure to refer to your owner's manual.

They are more expensive but they are less likely to be lost or stolen. They are also less vulnerable to being hacked as hackers do not find the radio frequency identification codes required for hacking.

A new key with blades is a more affordable alternative to replacing your key. It can be kept inside the fob. This allows you to keep your key hidden from view, so it won't be subjected to the same weather damage as the fob.

Replacement Programming Key

If you require a replacement key fob for your bmw, there are some things you should be aware of prior to beginning the process. The most important aspect is how to program the new key.

Although this can seem daunting for certain drivers, it's extremely simple and takes just 15 minutes. Programming your vehicle yourself is a great means to save money on replacement costs.

The other is when you're starting from scratch with no working key. The service department at BMW of San Diego can show you how to program your BMW key in both instances!

The first step is to take your keys for your car that are working and the ones you want to program into your car. Make sure all windows and doors are closed. The next step is to insert your working key in the ignition and turn it to position 1. You should see your dash lights and other indicators appear, but the engine should not be running.

Once the key is in the position 1, remove it of the ignition, and then reset it to the zero position. This procedure can be repeated for all key fobs.

Once all keys are programmed, you can use your new key for locking and unlocking the door. This will allow you to get back on the road in Longmont as soon as possible!

You can also use the replacement key to pair it with your BMW. This process is similar to how you would connect your iPhone with a remote, however, it's using NFC technology. The result is a set of keys that can be used with your BMW and also provide access to the vehicle's Comfort Access features.


These steps can be used to program one key or several keys. Keep in mind that the sync process for each key will only be completed within thirty seconds of the original key being changed.
