If the key tag signal appears to be unreliable, this may be due to a low battery. You can replace the battery yourself. The tag requires a flat CR2450 disc or button battery.
Tip
- You may find it helpful to use a small screwdriver to unlock the tag lid and to lift the battery from its slot.
Important
- For safety reasons and to ensure optimal battery performance, use hand protection such as a medical glove when handling a new battery.
- Used batteries must be recycled in an environmentally sound manner.
Warning
Check that the battery is fitted correctly with the correct polarity. If the key tag will not be used for a long time, remove the battery to avoid battery leakage and damage. Batteries with damage or leaks may cause corrosive injury on contact with the skin. Therefore, use protective gloves when handling old or damaged batteries.
- Keep batteries out of the reach of children.
- Do not leave batteries lying around since they can be swallowed by children or pets.
- Batteries must not: be dismantled, short-circuited or thrown into open flames.
- Do not try to charge non-rechargeable batteries. They may explode.
- Check battery operated products for signs of damage on a regular basis. The key tag should not be used if anything indicates that the tag or its battery has been damaged or has started to leak.
- Keep defective products out of the reach of children.
Hold the tag with the Volvo logo facing upwards. There is a small opening on one of the tag's short sides. Pry open the tag from this side by pulling the edge outwards and upwards.
Lift the tag lid to access the battery.
Pry the battery from the locking teeth and slide it towards you to remove it.
Slide the new battery into the slot and press it down to lock it into place. Make sure the positive side of the battery is facing upwards.
Close the tag lid so that it clicks into place.
If the key tag signal is still unreliable, this may be due to signal interference outside of the car. If the tag fails to work at all, repeat the steps and ensure that a fully-charged battery is properly installed. If you think that you may need a new key tag, contact Volvo support.
