Hoping someone can confirm this works for a newer Lem Four X Pro R.

I have the same Lem Four X Pro R and I'm also trying to find the key code.

Just tried this on my Lem Four X Pro R—anyone else have success?

Still can’t find the code for my Lem Four X Pro R. This might do it.

🔑 Car Key & Fob FAQ

Common questions about key programming, fob issues, and replacement options

Key Fob Issues
1) Find the seam and pry open the fob (some have tiny screws) 2) Note battery orientation 3) Remove old battery (CR2032 is most common) 4) Insert new battery 5) Reassemble. Test all buttons - if issues remain, the fob may need reprogramming.
Key Tip: Some locksmiths offer mobile key programming services

Key Tip: Keep spare keys in a faraday bag to prevent signal amplification theft
Lost Keys
Yes, a skilled auto locksmith can extract the broken key and make a replacement. They can often do this without damaging the ignition cylinder. The new key will need programming if it has a transponder chip.
Key Tip: Avoid exposing key fobs to water or extreme temperatures
Key Programming
Some vehicles allow DIY key programming using specific sequences (like turning ignition on/off with original keys). However, most modern cars require specialized equipment only locksmiths or dealers have. Check your owner's manual for your specific model.
Key Tip: Some locksmiths offer mobile key programming services
Key Programming
Most transponder keys and smart keys can be reprogrammed if they haven't been damaged. Basic mechanical-only keys (no chip) can't be reprogrammed - they must be physically cut to match your locks.
Key Fact: The average driver will lose 1-2 car keys during ownership
