These two LeeCrynoid VL2020 3V 20mm batteries with a 90° leg are direct-fit replacements made to restore power to compatible BMW key fobs.

If your BMW remote has stopped responding, the culprit is often a worn battery that looks like a small cylindrical VL2020 cell with a 90° solder leg. This 2-pack from LeeCrynoid matches the original dimensions and electrical specs so you can replace the worn part without altering the fob’s contacts or housing. The cells carry standard safety certifications and come with customer support in case installation raises questions.

Which BMW key fobs will these VL2020 batteries work in?

These VL2020 cells are engineered to fit a wide range of BMW key fobs across several model families. Confirm fit by checking your original battery’s 20mm length and the 90° solder-leg orientation before purchasing.

• Compatible examples: 3 Series (E46, E90/E91/E92/E93)
• Also fits 5 Series (E39, E60/E61) and 7 Series (E38)
• Works in X Series (E53 X5, E83 X3), Z4 (E85/E86), and 1 Series (E81/E87)

How do the specs and design benefit my key fob?

The VL2020 specification provides the proper 3V output and a compact 20mm form factor so contacts meet reliably within the fob. The 90° leg replicates original mounting geometry to prevent misalignment and intermittent connections that cheaper flat cells can cause.

• 3V nominal voltage for stable remote operation
• 20mm length and 2.0mm diameter for a snug mechanical fit
• 90° solder leg ensures correct placement and secure contact

What installation steps and skills are required?

Replacing a VL2020 in a BMW key fob typically requires opening the fob shell and desoldering the old cell before installing the new one. Basic soldering experience and steady hands are recommended; if you’re unsure, a locksmith or electronics technician can perform the swap quickly and safely.

• Open the fob carefully to avoid damaging plastic clips
• Desolder the old battery and solder the new VL2020 90° leg in place
• Test functions before fully reassembling the housing

Are these batteries safe and how long will they last?

LeeCrynoid VL2020 cells meet common safety standards for battery manufacturing and include protections against overheating and shorts. Expected lifespan depends on usage and fob design, but these cells match OEM specs so longevity will be similar to original replacements.

• Certified to FCC, RoHS, and CE quality and safety standards
• Protection against over-discharge, overheating, and short circuit
• Typical life comparable to factory VL2020 cells under normal use

Who is this for: This 2-pack is ideal for BMW owners, locksmiths, and DIY auto technicians who need an exact-form VL2020 3V replacement with a 90° leg. Choose these cells if your fob uses a 20mm VL2020 and you prefer a certified replacement that mirrors the original battery’s shape and electrical performance. If you lack soldering experience, consider professional installation to avoid fob damage.
