Land Rover Defender: Smart key battery replacement
When the battery needs replacing, there is a significant decrease in the effective range and the instrument panel displays a warning message.
To replace the battery:
- Push the button on the smart key.
- Pull the emergency key blade in the direction of the arrow.
- Use the emergency key blade to separate the smart key's body.
- Fit a new and unused CR2032 type battery, available from a retailer/ authorized repairer, with the positive (+) side upward.
Note: Avoid touching the new battery.
Moisture or oil from fingers can reduce battery life and corrode the contacts.
Note: If the low battery warning does not extinguish, it indicates that the replacement battery is not in a new or unused condition.
Refit the parts in reverse order. Make sure that the parts click securely into place.
Battery disposal: Batteries
contain harmful substances and
must be disposed of correctly.
Seek advice on disposal from a retailer/authorized repairer and/ or the local authority.
SMART KEY CARE
To prevent accidental or unauthorized operation, never leave the smart key unattended in the vehicle. Never leave children or animals unattended in the vehicle. The vehicle can be operated when the smart key remains inside the vehicle. Unintended or accidental vehicle operation could cause injury or death.
Do not expose the smart key to extremes of heat, dust, or humidity. Extreme heat, dust and humidity may damage the smart key.
Do not allow the smart key to come into contact with fluids. Fluids may damage to the smart key.
Do not leave the smart key exposed to direct sunlight. Sunlight may cause damage to the smart key.
The emergency key blade number is recorded on an attached label. Peel off the label and store it securely away from the vehicle.
The operational range of the smart key depends on atmospheric conditions and interference from other transmitting devices.
Note: The Radio Frequency (RF) used by the smart key may be used by other devices, e.g., medical equipment. Use of these devices may prevent the smart key from operating correctly.
The instrument panel displays a warning if the smart key battery is depleted. If a smart key low battery warning occurs, replace the batteries in all of the smart keys. Replacing all of the smart key batteries prevents permanent damage to the smart keys.
