Car Remote Control Key Battery CP-VL20 3V 20 to 50mAh Replacement
If your car key fob has become less responsive or requires you to stand closer to the vehicle, the internal battery may be low. This CP-VL20 remote control key battery is a direct replacement for compatible car key remotes, offering a nominal voltage of 3V and a capacity range of 20 to 50mAh to restore normal function. Designed as a simple swap-in component, it helps you avoid the cost of a complete key replacement. The battery is supplied as a single unit, making it a practical purchase for one-key households or as a spare.
Features and Construction
This battery is built to meet the CP-VL20 specification, ensuring it fits securely inside standard remote key housings. Its lithium chemistry delivers steady power within a compact form factor.
Material and Build
The lithium-based coin cell construction provides a stable voltage output of 3V, which is critical for consistent remote key performance. The battery is manufactured to industry-standard dimensions for the CP-VL20 type, so it sits correctly in the key fob tray without loose contact.
Size and Practical Fit
With a nominal capacity of 20 to 50mAh, the battery supports the short-range radio signals that unlock doors, open boots, or activate the panic alarm. Its low-profile design fits easily inside most remote key housings that accept the CP-VL20 format. The battery weighs only a few grams, making it a light addition to your keychain.
Uses and Placement
This battery is intended for automotive remote key fobs that require a CP-VL20 cell. It can also be used in compatible garage door openers or proximity cards that share the same battery specification.
Car Remote Key Use
When your existing remote key battery runs flat, swapping in this CP-VL20 cell restores the ability to lock, unlock, or start the car from a standard range. It works with most remote key systems that list CP-VL20 as the required battery type.
Everyday Convenience
Having a spare CP-VL20 battery on hand means you can replace a failing fob battery immediately, avoiding the inconvenience of being locked out. The installation process takes only a few minutes and requires no soldering or special equipment.
Benefits and Buying Value
This battery offers a straightforward solution for restoring remote key function without visiting a dealership. Its known voltage and capacity specifications give you clear expectations of performance.
Reuse and Low Maintenance
Once installed, the battery requires no maintenance until its capacity is exhausted. Replacement intervals vary by usage, but having a compatible spare ensures you are prepared. The battery is a cost-effective alternative to replacing the entire key housing.
Why Choose This Product
The CP-VL20 battery is a standardised replacement part, so you know it fits correctly. It is sold as a single unit, which is ideal if you only need one battery. With clear specifications—3V nominal voltage and 20–50mAh capacity—you can be confident it matches the requirements of your remote key fob.
