Car Ignition Repair in London — What We Offer
Ignition problems are among the most stressful mechanical faults a driver can face — your car simply will not start, and often no warning is given. Keylux mobile ignition specialists diagnose and resolve the full range of ignition faults on site.
The ignition system in modern vehicles involves more than just a mechanical barrel. It incorporates the immobiliser ECU, the transponder reader ring, and — on push-button start vehicles — proximity sensors and drive authorisation modules. A fault in any one of these components can prevent the vehicle from starting, even if the key itself is in perfect condition.
Our mobile technicians carry the diagnostic tools to identify whether your ignition fault is mechanical, electronic, or a combination of both — and carry out the appropriate repair at your location. In many cases, what appears to be a complete ignition failure is resolved with a barrel replacement and fresh key programming in a single visit.
All ignition work is quoted transparently before we begin. For general pricing information, see our key replacement cost guide. To get a specific quote for your vehicle, call us and describe the fault — we will advise before dispatching.
Ignition Barrel Replacement
A worn, seized, or damaged ignition barrel is replaced on site with a new unit, matched and programmed to your existing key where possible.
Broken Key Extraction
A snapped key inside the ignition barrel is removed cleanly using specialist extraction tools — without damaging the barrel itself in most cases.
Ignition Fault Diagnosis
We use OBD diagnostic tools to identify whether the ignition fault is mechanical, electronic, or immobiliser-related, and advise the best repair route.
Key Programming After Repair
After a barrel replacement, any existing or new keys are programmed to the repaired ignition system — all in one mobile visit.
Ignition Switch Repair
If the ignition switch — the electrical component behind the barrel — is faulty, we diagnose and advise on repair or replacement options on site.
Common Ignition Problems We Repair in London
Recognise your problem? These are the ignition faults our mobile technicians resolve every day across London.
The key inserts correctly but refuses to rotate. Often caused by a worn barrel, debris inside the lock, or the steering column lock engaging. Do not force it — this can cause additional damage.
The key rotates freely but the engine does not respond at all. This typically indicates an ignition switch failure, wiring fault, or a complete transponder mismatch with the ECU.
A key that has snapped inside the barrel leaves you unable to start the car or remove the broken fragment. Attempting to extract it yourself with pliers risks pushing it deeper. We extract cleanly with specialist tools.
A stiff barrel is often early-stage wear — a warning sign that failure is coming. A loose barrel indicates internal component wear. Both are resolved with barrel replacement before they strand you.
If the key turns but the immobiliser warning light stays illuminated and the engine won't fire, the transponder inside the key has likely lost its pairing with the ECU. This is a programming issue rather than a mechanical barrel fault. See our transponder key programming page for more detail.
The barrel will not accept the key at all, or the key inserts but is completely immovable. Usually caused by extreme wear, debris, or damage. Barrel replacement is required — we carry the most common replacement units.
Intermittent ignition faults are often caused by a partially worn barrel or a failing ignition switch. Intermittent problems tend to become permanent without repair — we diagnose on site and advise accordingly.
The steering column lock is mechanically linked to the ignition barrel on many vehicles. If the wheel locks up and the key won't turn, the issue is often the steering column lock rather than the barrel itself. We diagnose and resolve both.
⚠️ Do Not Force a Stiff or Seized Ignition
Forcing a key in a stiff or resistant ignition barrel is one of the most common causes of a snapped key — turning a manageable repair into a more complex and expensive extraction job. If your ignition feels stiff, loose, or unresponsive, call us before attempting to force it. We will diagnose over the phone and advise the right course of action before dispatching.
How We Diagnose and Repair Your Ignition
A structured, methodical approach that identifies the root cause before any repair begins.
Phone Assessment
You describe the symptoms. We narrow down likely causes before we arrive — saving time on site.
Mobile Dispatch
A technician is dispatched with the diagnostic tools and common replacement parts for your vehicle.
On-Site Diagnosis
We carry out a full mechanical and electronic assessment of the ignition system to identify the exact fault.
Quote & Approval
We explain the fault clearly, confirm the fix required, and give you the exact price before we start.
Repair & Test
The repair is carried out on site. We test fully before leaving — you drive away with a fully working ignition.
ℹ️ What if Parts Need to Be Ordered?
For less common vehicle makes or older models, a specific ignition barrel may need to be sourced. In most cases this is a same-day or next-day turnaround. We will confirm availability when you call — and we never begin chargeable work without your approval of the full price and timeline.

Frequently Asked Questions — Car Ignition Repair London
Common questions from drivers experiencing ignition problems across London.
The most common causes are a worn or seized ignition barrel, debris inside the lock cylinder, or the steering column lock engaging incorrectly. In some cases it can also be caused by a key that has worn to the point where it no longer engages the barrel correctly. Do not force the key — call us and describe the symptoms, and we will advise the most likely cause and the appropriate fix before dispatching.
In most cases, yes. We use specialist extraction tools designed to remove broken key fragments cleanly without damaging the barrel itself. Whether the barrel also needs replacing depends on its condition — we will assess this on site and advise you clearly before proceeding with any additional work.
The ignition barrel is the mechanical cylinder into which you insert your key. Over time — typically after many years or high mileage — the internal wafers and springs that make up the lock mechanism wear down. This causes the barrel to become stiff, loose, or eventually fail entirely. Replacement restores smooth key operation and prevents the vehicle from being stranded due to a complete barrel failure.
In most cases, an ignition barrel replacement is completed within 60 to 120 minutes on site. The exact time depends on your vehicle make, model, and dashboard configuration, as well as whether key programming is required afterwards. We always provide a realistic time estimate before we begin.
This depends on the type of replacement barrel fitted. In some cases a barrel can be recoded to work with your existing keys. In others, a new key must be cut and programmed to the replacement barrel. We carry key cutting and programming equipment in our mobile units, so this can be handled in the same visit. We will advise you on the exact process for your vehicle before we start.
Not necessarily a barrel problem. If the key turns but the engine does not respond, the fault may be with the ignition switch (the electrical component behind the barrel), the transponder chip in the key, or the vehicle's immobiliser ECU. We diagnose all three as part of our on-site ignition assessment. If the immobiliser light is illuminated on your dashboard, see also our transponder key programming page.
The cost depends on the specific fault, your vehicle make and model, and whether key programming is required after the repair. Broken key extraction alone is typically less expensive than a full barrel replacement. We always confirm the exact price before any work begins — there are no surprise charges. For a general guide to auto locksmith pricing, see our cost guide, or call us for an immediate quote.
In most cases, yes. Garages and dealerships carry higher overhead costs that are reflected in their labour rates. As a mobile service, Keylux provides the same quality of ignition repair without the garage markup — and without requiring you to arrange a tow. Read our locksmith vs dealership guide for a full comparison.
Stranded Due to an Ignition Fault Right Now?
If your car will not start due to an ignition problem, here is exactly what to do:
- Do not force the key. Forcing a stiff or seized ignition is the most common cause of a snapped key, which significantly increases the complexity and cost of the repair.
- Check the steering wheel. If the wheel is locked hard to one side, the steering column lock may be engaged. Try gently turning the wheel left and right while rotating the key — this often releases it.
- Do not call a recovery service first if you are in a safe location. A mobile ignition repair is almost always faster and cheaper than a garage tow and repair.
- Call Keylux. Describe exactly what the car is doing — or not doing — and we will diagnose over the phone, confirm the likely fix, and dispatch a technician immediately.
