Lexus Car Key Replacement in North London
Whether your Lexus keys are lost, stolen, broken, or you simply need a spare, we provide on-the-spot key cutting and programming for most models and years. That includes laser-cut “high-security” blades and proximity smart keys for push-button start models.
- Lost or stolen keys: We can create new keys from scratch, then remove the missing keys from your Lexus immobiliser so they can’t be used to start the car.
- Broken or damaged keys: We repair or replace blades, housings, and remotes, and we can extract a snapped blade safely from the door lock or ignition where relevant.
- Spare keys: A spare saves stress and money if your only key goes missing. We cut and code spares while you’re at home or work.

Lexus Key Programming and Smart Key Solutions
Modern Lexus models use encrypted immobiliser systems and Smart Key Systems (SKS) that require specialised tools and know‑how. Our technicians are trained in Lexus/Toyota platforms and use dealer-level diagnostic equipment to code transponders, remotes, and proximity fobs correctly.
- Transponder key programming: For models with a metal blade and chip, we program the immobiliser via OBD2 or, in “all keys lost” scenarios, using secure EEPROM techniques on the immobiliser/ID box modules.
- Smart key programming: For push-to-start Lexus (e.g., RX, NX, UX, ES, IS), we add or replace smart fobs, pair them with the Smart ECU/ID box, and run synchronisation routines so start/stop and keyless entry work reliably.
- Key data reset and key deletion: When keys are lost or stolen, we can erase them from the system and register new ones—an important step for peace of mind.
- Battery and remote issues: We test key batteries and RF output, replace shells or buttons, and re-synchronise remotes where needed.

How Our Mobile Lexus Auto Locksmith Service Works
- Quick contact and quote: Tell us your Lexus model, year, location (e.g., N1 Islington, N10 Muswell Hill, N12 North Finchley, N22 Wood Green), and the issue. We’ll provide a clear, no-obligation estimate.
- Ownership check: For your security, we’ll ask for proof of ownership/ID before creating keys or unlocking the vehicle.
- Dispatch: A DBS‑checked technician is assigned and heads out in a fully equipped mobile unit. We cover North London widely, including Highbury, Highgate, Barnet, Tottenham, Enfield, Palmers Green, Bounds Green, Stoke Newington, and beyond.
- Diagnosis: We run dealer-level diagnostics on the immobiliser/ECUs via OBD2. For “all keys lost” on certain Lexus systems, we may remove a small module for safe bench work (EEPROM) to generate a new working key.
- Cutting and coding: We cut high-precision laser keys and code the transponder/smart fob. Where required, we also perform key erasure to block lost or stolen keys.
- Testing and handover: We test door locking, remote functions, and start/stop. You leave with clear advice on care and a written warranty.

FAQs
Can you make a new Lexus key without the original?
Yes. We can create new Lexus keys when all keys are lost. Depending on model and year, this may be done via OBD2 programming or, on certain systems, by reading immobiliser data using secure EEPROM methods. We’ll advise the best route for your car and explain it simply.
Can you programme a used Lexus key fob?
Sometimes, but not always. Many Lexus smart keys become “locked” to the original vehicle. In some cases, specialist procedures can reset them, but success depends on the fob and vehicle generation. We can quickly assess your fob and advise if a new OEM/OE-quality fob is the better option.
How long does Lexus key replacement take?
It varies by model and whether you have at least one working key. Adding a spare can be relatively quick. All-keys-lost scenarios, Smart ECU/ID box synchronisation, or EEPROM work take longer. We’ll give you a realistic timescale once we confirm your Lexus model and the work required.
Will you damage my Lexus when unlocking or programming?
We use non-destructive entry methods wherever possible and professional diagnostic procedures that are safe for your car. On rare occasions where damage is unavoidable (for example, a severely damaged lock), we’ll discuss it with you first and get your approval.
My Lexus says “Key Not Detected.” What should I do?
Try a fresh key battery and hold the fob next to the start button (some models have an emergency start coil). If that doesn’t work, it may be an antenna, key, or Smart ECU synchronisation issue. We can diagnose and repair these faults on-site.
How much does a Lexus key cost?
There isn’t a one-price-fits-all answer. Costs depend on the model, year, key type (blade, remote, smart), and whether it’s a spare or an all-keys-lost situation. For clarity on your specific car, ask us for an accurate, free estimate. You can also learn how we price work on our auto locksmith prices North London page.
