Before ordering, confirm that your remote requires the CP-VL20 specification to ensure a correct fit.
Features and Construction
This battery is built around the CP-VL20 standard, a common format for automotive remote keys. Its lithium chemistry supports the low continuous drain typical of key fob circuits.
Lithium Chemistry
The battery uses lithium as its active material, providing a stable voltage output of 3V for consistent performance in key fob electronics. This chemistry is suited to devices that require a small, lightweight power source without frequent replacement.
Standardised Format
The CP-VL20 specification ensures compatibility with a range of car remote control keys. Its physical shape and terminal arrangement match many factory-installed batteries, making installation straightforward without adapters or modifications.
Uses and Placement
This battery is intended primarily for car remote control keys, but it may also suit other small electronic devices that use the same form factor.
Vehicle Keyless Entry
Its main application is in key fobs for locking and unlocking cars from a distance. A fresh CP-VL20 battery restores normal range and response time to your remote, eliminating the need for manual key operation in most conditions.
Everyday Home Use
Beyond vehicles, this battery can power other low-drain devices that accept the CP-VL20 size, such as some garage door openers or small access control remotes. Always verify the device's battery specification first.
Benefits and Buying Value
Choosing the correct replacement battery saves time and avoids the expense of a new key fob. This CP-VL20 model offers a simple, cost-effective solution for restoring remote functionality.
Reuse and Low Maintenance
Replacing a key fob battery is a low-effort task that can be done at home without specialist tools. A single battery typically provides months of normal use, reducing the need for frequent changes.
Why Choose This Product
This battery matches the exact CP-VL20 specification commonly found in car remotes. Its 3V lithium construction delivers the correct voltage for reliable operation, and the 20-50mAh capacity meets the typical energy requirements of key fob circuits. For anyone with a non-responsive remote, it is a practical, targeted replacement part.
