When You Need a Lexus Auto Locksmith
Lexus vehicles feature advanced immobiliser systems and smart keys. When something goes wrong, it can be stressful—especially if you’re away from home. Common situations we help with include:
- Lost or stolen Lexus keys (no spare available)
- Locked keys in the car or boot
- Smart key not detected / “Key Not Detected” message on dash
- Lexus won’t start with Start/Stop button
- Broken or damaged Lexus key blade or flip key
- Key fob not responding after battery change
- Central locking not working or intermittent unlock issues
- Key stuck in ignition (older Lexus with blade ignition)
- Worn or snapped Lexus key, or damaged remote buttons
If you’re locked out, we provide non-destructive entry wherever possible, using professional tools to protect your vehicle. We’ll explain any rare exceptions before starting work.
For urgent help with a lockout or roadside issue, see our dedicated Emergency Auto Locksmith in Twickenham.
Lexus Key Replacement and Programming Made Simple
We offer a full mobile solution for modern Lexus keys and immobilisers, using dealer-level diagnostics and specialist tools.
- Lexus Smart Key Replacement
- We supply and program replacement Lexus proximity/smart keys for push-to-start models. A smart key is the fob that allows keyless entry and push-button start.
- Transponder Key Programming
- A transponder is a small chip in your key that talks to your car’s immobiliser. We handle transponder programming via OBD2 where appropriate and EEPROM methods for models that require it.
- Remote Key Fob Programming and Repair
- If your Lexus fob has stopped working, we can diagnose, repair buttons, replace shells, or program a new remote.
- Key Cutting and Key Blade Replacement
- Precision cutting for Lexus emergency blades and laser cut profiles.
- ECU / Immobiliser Programming
- Advanced immobiliser pairing and module work when keys are all lost or systems are locked, including EEPROM key programming where necessary.
- Non-Destructive Vehicle Unlocking
- Professional entry to protect paintwork and weather seals, ideal for keys locked in the boot or cabin.
If you only need a spare key for convenience or peace of mind, we can cut and program on-site. Explore more about our Car Key Replacement and Car Key Programming services.

Frequently Asked Questions
Can you make a new Lexus key without the original?
Yes. We can create and program a new Lexus key without the original using dealer-level diagnostics. For some models, we may use EEPROM/immobiliser programming. Proof of ownership is required.
Will you have to damage my Lexus to unlock it?
No—our vehicle unlocking is non-destructive wherever possible. In rare cases where a different approach is needed, we’ll explain why and get your approval first. Learn more about our Vehicle Unlocking.
How long does Lexus key replacement take?
Often we complete same-visit replacements because we’re mobile and carry the right tools. Timing depends on your model, key type (smart vs blade), and whether all keys are lost.
Can you program a Lexus smart key I bought online?
We can attempt to program customer-supplied keys, but compatibility varies with Lexus models and immobiliser generations. For the most reliable outcome and warranty, we recommend keys we supply.
My Lexus says “Key Not Detected.” What should I do?
Try a fresh key fob battery and hold the fob close to the start button. If it still won’t start, there may be a programming, antenna, or immobiliser issue. We can test and resolve it on-site with Car Key Programming.
Do you cover business and fleet Lexus vehicles?
Yes, including company cars and mixed fleets. We also support vans and commercial vehicles—see our Van & Commercial Locksmith service.
