How to Unlock Your Vehicle

Modern electronic key fobs offer greater functionality and comfort compared to traditional manual keys. Batteries will eventually get worn out and will require replacement. If your Volvo key fob has begun to malfunction intermittently, it's an indication that the battery is depleted and will need replacing soon.

Fortunately, there are simple steps you can follow to replace your Volvo key fob battery on your own. Choose a clean, dry surface to work on. Place all the tools you will need. Locate the battery hatch and make sure it is set to "open." Use a flathead screwdriver or coin or a similar tool to turn the hatch wide. Then, carefully pull out the battery by lifting the side closest to the hook on the key-ring. Be sure to use rubber gloves to protect the contacts or the clips.

After the battery is removed, insert the new one in its socket. Make sure that the positive end of the battery is facing up, and that all clips are secured. Slide the cover toward the key-ring portion until it becomes loose, and is able to slide off. Then, remove the cover to reveal the hidden key blade. It can be used to unlock your vehicle by the driver's side doors in the event that the key fob battery is dead or missing.

How to Start Your Vehicle

Modern vehicles come with keyfobs which do more than simply unlock and lock the doors. They can also be used to perform functions such as summoning and auto parking the vehicle. The brand new Volvo XC60 is capable of remotely starting your engine via the key fob buttons. How does it work exactly?

First, find G28 on which you can lay out all the necessary items for this project. Then lay the fob on the work surface, with its Volvo logo facing upwards. Use a flathead, coin, or any other similar tool to open the battery hatch. Avoid touching the electronic contact surfaces with your tools. This could cause the fob to stop functioning properly.

Once the hatch is open then slide the battery into its socket and ensure it is correctly seated with the positive (+) side facing up. Once the clips have been locked into place, replace the cover of the battery and then reassemble the fob.

By pressing the unlock button only one time and the alarm will disengaged and the driver's door will be unlocked. If you press it again it will unlock all doors as well as the tailgate. The unlock button is also useful for opening the windows to let in cool, fresh air in the summer heat. If you're in the market for more, the key fob can also be used to activate ERS, which will activate the climate control system in your vehicle and warm or cool it to the desired temperature setting when the vehicle is stationary.

How do I replace the battery?

If your key fob isn't locking or unlocking your car as it did in the past, it may be time to change the battery. The battery can be replaced by using a flathead screwdriver pry bar made of plastic, or other small tools. Find the small hole that used to house the backup/emergency ignition key made of steel. Insert the blade of a screwdriver or prybar tool into this slot, and gently push the rear of the fob open. After you have opened the fob, you can locate and remove the CR 2032 3V battery. Place a new battery in its spot and put the fob back together.

Note: Older Volvos use a different battery which is the CR2025. CR2025 batteries are 7 10ths of a millimeter smaller than a CR2032 battery, and you'll need to be extra careful when placing the battery of the replacement.
