Mobile ignition, switch and steering lock specialists in Thornton Heath
Ignition and steering lock faults are among the few problems that immobilise a vehicle completely while leaving almost no external clue as to the cause. Correct diagnosis before anything is replaced matters more here than on nearly any other job.
The visit begins with diagnosis, not with a quote for a replacement. Getting that first step right is what decides whether the job turns out to be a rebuild, a switch, an emulator or a full replacement.
Station car parks and village halls in places like Thornton Heath are common call-out spots. An on-site repair is usually simpler than waiting for recovery out of a tight space.
Why the fault needs identifying before anything is replaced
Because the symptoms of a worn barrel, a failed switch and a jammed column lock are so similar, guesswork is expensive. We test to establish which component has actually failed rather than fitting the most likely candidate and seeing what happens.

How a Thornton Heath call-out actually runs
From your first message to a working key, the job breaks down into four steps.
Tell us what it is doing
Call or message with the make, model, registration and what the key or wheel is doing. That usually tells us which parts and programming to bring.
We come to the vehicle
We attend wherever it is standing. We attend anywhere in Thornton Heath or the wider CR7 area. We work where the vehicle is, not where it would be convenient for a workshop.
Diagnose, then repair
We establish whether the fault is the barrel, the switch, the steering lock or the key, explain what we have found, and then rebuild, replace or programme as needed.
Test and hand back
We check the ignition, the steering lock release and the immobiliser all behave correctly before we leave, and the work is covered by a parts and labour warranty.
Covering Thornton Heath and the CR7 area
Our Thornton Heath work takes in Thornton Heath, Norbury edge, Thornton Heath Pond, High Street and the CR7 residential streets.
Cul-de-sacs, gated drives and narrow village streets are all workable locations for us. No workshop, no ramp, no queue. The vehicle stays where it is and we come to it.
We are based at Greenhedges, Felcot Road, East Grinstead, West Sussex RH19 2QA, which puts Thornton Heath comfortably within our regular working area.
Ignition stuck right now?
Stop turning it before something breaks. Ring us and tell us what the key and the wheel are doing. We cover Thornton Heath and the CR7 area.
Ignition and steering lock FAQs for Thornton Heath
What Thornton Heath customers ask first — barrel, switch, steering lock and nearby coverage.
Do you repair ignition barrels and steering locks in Thornton Heath?
Yes. Mr Ignition is a mobile ignition barrel replacement and steering lock repair service covering Thornton Heath (CR7) in London, including Thornton Heath. We diagnose at the vehicle — driveway, workplace, car park or roadside — from our East Grinstead base.
Is a locked steering wheel in Thornton Heath the ignition barrel or the steering lock?
It can be either, so we diagnose rather than guess. A stiff or immovable key points at the barrel. A key that turns normally with a locked column or a dash warning points at steering lock repair or an electronic steering lock. The Knowledge Centre explains how those faults differ.
Can you extract a snapped key in Thornton Heath?
Yes. broken key extraction is routine work in Thornton Heath. Leave the broken section alone — an undisturbed barrel can often be saved. Forcing, drilling or hooking the fragment is what turns an extraction into a replacement.
Which towns near Thornton Heath do you cover?
As well as Thornton Heath we regularly cover Croydon, Crystal Palace and Forest Hill. The same mobile visit covers ignition barrel replacement, ignition switch replacement and steering lock repair. See every live page on areas we cover.
Do you programme Ford, Mercedes and other electronic steering locks in Thornton Heath?
Yes, on supported vehicles. That includes Mercedes ESL and EIS and ESL emulator programming for Ford, Renault, Nissan, BMW, MINI, Hyundai, Kia, Vauxhall and other listed makes. We confirm the lock at the vehicle in Thornton Heath before any module or emulator is programmed.
Can my Thornton Heath ignition barrel be rebuilt onto the existing key?
Often, yes — a rebuild is the first option we look at. It keeps your existing key and avoids immobiliser work. If the barrel is too far gone we replace it on supported cars and say so before starting. Related part references sit on the ignition barrel replacement page.
Is there a call-out fee for Thornton Heath?
No call-out fee. You are quoted for the diagnosed repair, not for us arriving. Call or get in touch with the registration, the fault and the Thornton Heath postcode.
Is ignition work in Thornton Heath guaranteed?
Yes. Parts and labour are warranted. Before we leave Thornton Heath we check the ignition, steering lock release and immobiliser together so the vehicle is confirmed as a system, not just at the repaired part.
Why ignition barrels fail, and what it feels like when they do
Barrels fail through ordinary mechanical wear. The wafers the key lifts wear down, the springs behind them lose tension, and decades-old grease hardens into a paste that resists movement rather than helping it.
Key condition matters more than most people expect. A worn blade sits slightly wrong in the barrel, loads the wafers unevenly, and quietly damages the lock a little more every time it is used.
If you have started thinking of it as a quirk rather than a fault, it is a fault. Barrels do not recover.
Vehicles we see this on most around Thornton Heath
Certain vehicles are simply over-represented. Ford Transit and Transit Custom, Volkswagen Golf and Crafter, Citroen Relay and Peugeot Boxer, plus Vauxhall, Honda, Hyundai, Audi and Mercedes-Benz. Campervans and horse boxes based on van platforms come up too, often with very high ignition cycle counts on low mileage.
Electronic steering locks: ESL, ELV and ESCL faults
Where an older car had a steel pawl and a cable, a modern one has a motorised module clamped to the column. It is a sealed electronic assembly, and when it fails it usually fails in the locked position.
Because the module lives inside the immobiliser system, you cannot simply swap in a used one from a breaker. It has to be programmed to the vehicle, and on some platforms an emulator is the more reliable long-term answer.
How to tell an ESL fault from a barrel fault
If the key feels wrong, suspect the barrel. If the key feels completely normal but the car will not release the wheel or start, suspect the electronic lock. Getting this right at the roadside is what stops the wrong part being fitted.
What to do right now if your key will not turn
Put the pliers down. Forcing a stiff barrel is how keys break, and a key broken off flush inside the cylinder is a materially harder and more expensive job than the original fault ever was.
These are worth two minutes of your time before you call us out.
- Rock the steering wheel gently while turning the key — the column may be loaded against a kerb or at full lock
- Make sure the vehicle is properly in Park, or in gear with the clutch down on a manual
- Try your spare key; if the spare works, the fault is the key rather than the barrel
- Check the key for visible wear, bending or a cracked plastic head
- Take heavy items off the keyring — weight on the barrel causes and worsens this fault
- Do not spray oil or lubricant into the barrel; it collects grit and makes the eventual repair harder
- Never lever or drill at a snapped key — extraction is far easier before anyone has dug at it
If the key has already snapped
Leave it exactly as it is and call us. Broken key extraction is routine work when the barrel has been left alone, and the lock very often survives to be reused. Once somebody has attempted a DIY extraction, the barrel usually has to be replaced instead.
Mobile repair or recovery to a garage?
A recovery truck solves a location problem, not a technical one. You still arrive at a workshop that has to diagnose the fault, and general garages often subcontract ignition and immobiliser work anyway.
Because access is from inside the vehicle rather than underneath it, a workshop offers no real advantage for this type of repair. We bring the diagnostic and programming equipment to you.
Not every job finishes on the first visit. Some parts have to be ordered and some units need bench work — but you will know that from us, after a proper diagnosis rather than instead of one.
What the work covers
What actually gets done depends entirely on the diagnosis. The realistic options are these.
- Barrel rebuild — worn wafers and springs replaced so the original key works again
- Barrel replacement — a new lock fitted, with key or immobiliser programming where required
- Broken key extraction — the snapped section removed and the barrel assessed
- Ignition switch replacement — for the electrical fault behind a barrel that turns normally
- Steering lock repair or replacement — mechanical and electronic column locks
- ESL / EIS programming — replacement modules matched to the vehicle, Mercedes included
- ESL emulator programming — a programmed alternative on supported platforms
Every visit finishes with the ignition, steering lock and immobiliser tested together, and the work carries a parts and labour warranty.
