Key Battery Outlet Tesla Model X Key Fob Battery CR2354 2-Pack — 3V OEM-Fit, Quick DIY Replacement

This 2-pack of CR2354 3V lithium batteries from Key Battery Outlet replaces the Tesla Model X key fob battery to restore reliable remote function and a precise fit.

When a Tesla Model X key fob begins to show low power—slower responses, reduced range, or intermittent unlocking—swapping the internal battery is the fastest, most affordable fix. These CR2354 cells are matched to the original specification used in the Tesla key fob, and the pack includes two batteries so you have a spare on hand. A video guide and straightforward installation make it a quick DIY task without tools for most owners.

How easy is it to replace the Tesla Model X key fob battery?

Replacing the CR2354 in a Model X key fob is designed to be simple and fast. Most people can complete the swap in minutes using the step-by-step video or a small flat tool to open the fob. No soldering or special equipment is required.

• Two batteries per pack—one installed, one backup.
• Quick-release fob seam or small slot access method.
• Video walkthrough covers removal, replacement, and resealing.

Will these CR2354 batteries work exactly like the original Tesla cells?

These batteries are manufactured to match the Tesla CR2354 3V specifications so voltage, size, and contact points align with the original cell. That ensures consistent performance and fit without modifying the fob. Longevity depends on usage, but the chemistry and construction mirror OEM expectations.

• 3V lithium chemistry consistent with Tesla specifications.
• Same diameter and height for secure seating in the battery holder.
• Stable voltage output for reliable remote signals.

Can I store an extra battery safely and how long will it last installed?

Uninstalled lithium coin cells store well when kept in a cool, dry place away from metal objects. When installed, typical lifespan depends on usage patterns—occasional locks/unlocks last longer than heavy daily use. Replacing at the first sign of intermittent operation prevents being locked out or losing remote functionality.

• Store spare cells in original packaging, separated from keys.
• Installed life commonly spans months to a few years depending on use.
• Replace promptly when range or responsiveness declines.

What tools or materials do I need to change the key fob battery?

Most Tesla Model X key fob battery changes require no special tools—only a small flat tool or fingernail to pry open the case. For those who prefer guidance, the included step-by-step install video clarifies each motion. Keep a microfiber cloth nearby to protect the fob finish while you work.

• Small flathead screwdriver or flat pry tool (optional).
• Microfiber cloth to prevent scratches on the fob housing.
• Access to the video guide via smartphone or computer for visual steps.
