The XC70 key fob offers the following functions:


As seen from above, aside from unlocking and locking your car, a key fob is very useful in many situations.

Possible Issues With a Key Fob

As with all electronic devices, key fobs can malfunction. This is unfortunate, as this will render the fob useless. If you are experiencing issues with your key fob, it is important to follow these pointers:


1) Try a backup remote

The first thing you should do is try to replace the key fob with a backup remote. This will allow you to narrow down the root of your key fob issues.


If your backup remote allows you to lock and unlock your doors, you will know that there is a problem with your main remote. In contrast, if your backup remote doesn’t work, it is possible that there is a mechanical or electrical problem with the door locks.


2) Check the key fob battery

This is the second thing you should do. The battery of your key fob should be replaced every three years. If it is out of date, the problem may be in the battery or the transmitter unit.


The majority of the car key remotes are powered by category 4 button cell batteries, and they are not expensive. Regardless, it is still a good idea to check the battery that your remote uses and see if it’s good.


There are a few ways you can determine which type of battery you need. What you should know should be listed in your owner’s manual. Alternatively, you may contact a local dealer. You can also open the remote and check the battery. Usually there will be a number printed or stamped on the surface of the battery.


3) Check the buttons

Check the buttons on your key fob. It’s possible that your key fob is malfunctioning because there is something wrong with the buttons. If you have already checked the battery, you should check the buttons next.


Make sure that they are not misaligned, and that they are not dirty. This can be done by using a small piece of cotton to clean them. Alternatively, you can clean them using rubbing alcohol and a toothpick.


If none of those options work, you might need to get them replaced by a professional technician. If there is something wrong with the buttons, you might have to replace them with new ones.


4) See if there’s any signal interference

This is another possibility. If there is a problem with the transmitter unit, it might be interfering with other electronic devices. For example, your key fob may be malfunctioning because of a nearby radio frequency.


In this case, you should try moving the key fob closer to your vehicle, or putting some distance between it and likely culprits of the interference, such as your smartphone. See if that changes anything. If not, it’s possible that you need to get a new transmitter unit.


5) Get your key fob reprogrammed

If none of the above work, there may be other problems with the remote, like broken battery contacts or a problem with the buttons. It’s also possible that your vehicle has forgotten the fob.


When you want a remote to work properly, it must be paired with the receiver unit in your car. This way, someone who has the same make and model of your vehicle can’t just go up and use their fob on your vehicle. If your vehicle has “forgotten” your key fob, you might need to get your key fob reprogrammed.


So, you will have to reprogram your car’s keyless entry system in order to restore your car key remote functionality. You can do this by turning the key in the ignition several times while the doors are closed. Additionally, you can consult an expert, as this is a service that many car dealers offer.


6) Buy a replacement!

Other options include buying a replacement remote from your local dealer, whether brand new or used. If you get a used one, you must reprogram the lock and unlock on your vehicle to make it recognize it.
