Tesla Roadster Ignition Lockset Barrel — Replacement
Roadster ignition locksets are reaching end of life. During higher-volume Roadster production, Tesla sourced a lockset different from the Lotus OEM part. We now stock the wear component—the ignition lock barrel (cast-aluminum housing).
Why it fails
Inside the assembly, the key tumbler uses a steel follower pin that rides on a cast-aluminum ramp in the barrel. Repeated use wears the ramp and eventually forms a divot, causing binding and incomplete key release.
Common symptoms
- Key won’t release cleanly from the tumbler
- Increased effort needed to turn the key
- No-turn condition even with jiggling or slight steering-wheel movement
What’s included
- Ignition lock barrel (cast-aluminum housing)
Note: Key tumbler/cylinder is also included.
Fitment
- Tesla Roadster (all years/variants using Tesla-sourced lockset)
Installation notes
- Remove steering-column plastic trim to access the assembly
- Transfer your existing tumbler and switch as required
- Typical install time: ~30–60 minutes for an experienced tech
Recommendation:
Replace the barrel before the key binds completely and you can no longer unlock or turn the ignition switch.
Early replacement prevents immobilization and collateral damage to the tumbler.
NOTE – The Tumbler shown contains replacement numbered wafers. To replace this assembly, and match it to your keys, you will need to disassemble the wafers carefully recording the numerical sequence, and respective placement.
