When You Need a Lexus Auto Locksmith
Lexus vehicles use advanced immobiliser and smart entry systems. That’s great for security, but it can be stressful when things go wrong. Call us if you’re experiencing:
- Lost or stolen Lexus keys in Croydon or nearby CR postcodes
- Locked keys in the car or boot, including deadlocked vehicles
- Lexus won’t start and shows a key symbol on the dash
- “Key Not Detected” or intermittent start on push-button models
- Faulty Lexus key fob, water damage, or buttons not responding
- Battery replaced but Lexus remote still not working
- Broken or worn emergency key blade for your smart fob
- Key snapped in the door or ignition, or the key won’t turn
- Central locking problems on one or more doors
- Need a spare Lexus key for peace of mind
If you’re unsure what you need, we’ll diagnose it on the spot. For common “fob not working” issues, see our guidance on key fob not working. For security concerns, see what to do with lost or stolen car keys.
How We Fix Lexus Key and Lock Issues
We use dealer-level diagnostics and careful, non-destructive techniques to resolve Lexus key and lock problems efficiently.
-
Non-destructive vehicle entry
- We use specialist lock picking and door entry tools designed for Lexus models. We avoid damage wherever possible and will explain any exceptions (for example, severely damaged locks) before proceeding.
-
Lexus key replacement and cutting
- We cut new Lexus keys and emergency blades using high-precision cutting machines for a perfect fit. This includes smart key emergency blades and high-security profiles.
-
Lexus smart key and transponder programming
- Using OEM-level tools and OBD2 diagnostics, we program transponder chips and smart keys. Many Lexus models use advanced Toyota/Lexus immobiliser systems (e.g., 8A/128-bit). We handle both spare keys and all-key-lost scenarios.
- For some older or complex cases, EEPROM/immobiliser programming may be required; our trained technicians handle this safely and securely on-site.
-
Push-to-start and proximity systems
- We diagnose and repair issues with “Key Not Detected”, proximity range problems, and start/stop authorisation faults. This may involve synchronising the Smart ECU/ID box or resetting immobiliser data with dealer-level equipment.
-
Fault finding and repairs
- We test fob batteries, antennas, and door control modules; repair or replace worn buttons and shells; and address ignition/lock faults. If there’s a stubborn lock or ignition issue, we can advise further or complete a repair where viable.
-
Warranties and assurance
- New keys and programming are covered by our warranty. We stand behind our workmanship and will always provide clear guidance on care and future spares.

Costs and Quotes for Lexus Keys
There isn’t a one-size-fits-all price because Lexus key systems vary by model, year, and key type. Costs depend on:
- Vehicle model and year (e.g., IS vs RX, 2012 vs 2022)
- Key type (remote, smart/proximity, emergency blade)
- All keys lost vs spare key programming
- On-site unlocking vs creating a key from scratch
- Timing (standard hours vs urgent/emergency)
We’ll ask a few quick questions and give you an accurate, no-obligation quote before we begin. For context, read about the factors on our auto locksmith prices Croydon page, then contact us for a tailored estimate.

Lexus Auto Locksmith FAQs
Can a locksmith make a Lexus key without the original?
Yes. With the correct tools and security verification, we can create and program a new Lexus key without the original. Depending on model/year, this may involve OBD2 programming or advanced immobiliser work (EEPROM). We’ll advise the best route when you call.
How long does Lexus smart key replacement take?
In many cases, we complete Lexus smart key replacement and programming in one visit. The time varies by model and whether you’ve lost all keys, but our mobile service carries the equipment to finish on-site efficiently.
Can you program a used Lexus key fob?
Sometimes, but not always. Many Lexus/Toyota smart keys are designed to be locked to the original vehicle. Certain models can be re-used if reset or “virginised” with specialist equipment. We’ll check your model and give honest advice on whether a used fob is viable or if a new fob is the safer choice.
My Lexus says “Key Not Detected.” What should I do?
Try your spare key (if you have one) and replace the fob battery. If the issue persists, it could be a fob fault, antenna issue, or immobiliser synchronisation problem. We can diagnose and fix this on-site with dealer-level tools.
Will you damage my Lexus when unlocking it?
No, our approach is non-destructive wherever possible. We use specialist tools to open Lexus vehicles without damage. In rare cases where a component is already damaged or seized, we’ll explain the options before proceeding.
Do you cover evenings and weekends?
Yes. We provide mobile coverage across Croydon and CR postcodes with efficient dispatch. If it’s urgent, call us and we’ll prioritise your job.
Do you guarantee the new Lexus keys?
Yes. Our Lexus keys and programming work are covered by warranty. We also offer clear aftercare advice to help you avoid future issues.
