Worked on my cousin’s Lotus Mark IV—might work for mine too.

🔑 Car Key & Fob FAQ

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

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: Replace key fob batteries every 1-2 years as preventative maintenance
Cost & Options
Quality aftermarket keys work well for most vehicles at lower cost. However, some luxury brands use proprietary technology only available through dealers. For expensive cars, OEM may be worth the extra cost for reliability.
Key Tip: Avoid exposing key fobs to water or extreme temperatures
Key Fob Issues
Sometimes. Broken buttons can often be fixed by cleaning or replacing the button pad. Cracked cases can be glued. However, water damage or circuit board issues usually require complete fob replacement. Reprogramming is still needed for replacement fobs.
