So long as you have the key, you are able to unlock the vehicle, open your trunk, sound your horn, and use the push-to-start feature from any of your fingertips.

Here are some tips on how to fix a Volvo XC40 key fob not working quickly.

Check on The Batteries

Make sure that your battery is fully charged and charged for at least 24 hours before using your Volvo XC40 key fob again. Do not leave it connected all the time if you do not need it. That will reduce its life span and eventually, it will stop working altogether. Always use it as soon as you need it because that is the only way it can last long enough for you to use it regularly until its lifespan runs out.


Remove the battery cover. Make sure that there is no corrosion or rust on the terminals of your battery that may have damaged them or blocked the battery canals. Furthermore, look for a loose connection on the battery terminals of your Volvo XC40 key fob. If you see corrosion, use a plastic opening tool to remove the corrosion or rust on the battery terminals and then wipe them clean with a clean cloth.


Check if there is any dirt or debris inside the battery compartment or engine compartment where your Volvo XC40 key fob is located. Use a small brush to clean all debris in that area so that it does not affect its performance when used again later on. Make sure that you do not use any sharp objects to remove debris as they may end up damaging other parts, causing more serious problems than just this key fob not working problem.


Make sure that there are no cracks in the plastic cover of your Volvo XC40 key fob. Check by gently pressing down on it with both hands and pulling it away from its housing carefully and slowly until you can clearly see the inside of the key fob and its contacts and their connections.

What to Do if the Key Fob is Broken

If you have a broken key fob, you can still refer to alternative methods to try out. Here are some tips on what to do about a broken key fob on a Volvo XC40.


Unlock it remotely

Volvo cars are likely to have remote door unlocking services, so that their owners can get in their cars when the fob is malfunctioning. You can refer to these services if you need to get into your car as soon as possible but your key fob is broken.


However, when you are driving a used Volvo car, it is possible that you might not have this advanced remote unlocking system.


You can still depend on a roadside assistance service to help you enter your house. Every manufacturer has a different service for dealing with emergency situations. When it comes to Volvo, the service is called Volvo on Call.


The people at Volvo on Call can provide remote unlocking services for lost or damaged Volvo XC40 key fobs and can teach you how to unlock your beloved Volvo without a key.


Replace the key fob battery

If your key fob is broken, you can try to replace the battery on it. It is relatively easy to do and can be done by most people.


All you need to do is pop the battery cover and open the key fob. You can get yourself a small tool, like a screwdriver, to help you achieve this. Remove the screws from the battery cover on your Volvo XC40 key fob. Gently pull off the cover and then remove the old battery.


The battery for a key fob looks like silver buttons, and there is always a set of numbers on them. Note the numbers and go shopping for a battery replacement. After you swap those key fobs, you should notice that the key fob is now functional again.


Replace the whole key fob

There’s always the possibility that the trouble lies in the whole key fob, instead of just the battery. In this case, if you are a licensed Volvo owner, there are ways to buy replacement key fobs from Volvo themselves.

To replace a Volvo key fob, the price range varies. They can range at about $250 to $400 for high-end vehicles, but it mostly depends on the make and model of the specific car, and the year it was manufactured.


If you can prove to them that you own the Volvo, another way to solve your key fob issue would be to hire a locksmith to program keys for your car. The locksmith will personally come out to cut new keys for your vehicle and program them to work.


Being that they are mobile, locksmiths generally have quicker turnaround times than typical repair centers. So instead, you may also refer to your preferred car service center that specializes in selling certain car parts and services.
