Quick answer: a key that's stuck or won't turn in the ignition is usually one of four things — the steering lock binding, a worn key, a worn ignition barrel, or a failed ignition switch. Two of them you can rule out yourself in under a minute; the other two we repair at your location from £150, call-out and labour included. Whatever you do, don't force it — call 07777 676261 with your registration and we'll tell you which one you've got.
Below: how to tell the four apart, what to try before calling anyone, what each fix costs, and what not to do while you wait.
Match your situation to the closest description — it points at the likely cause:
Two separate parts live in your steering column, and people get quoted for both when only one has failed:
The ignition barrel (also called the lock cylinder) is the mechanical lock your key goes into. Inside are spring-loaded pins or wafers that must line up with the cuts on your key before the cylinder can rotate. It's the most-used lock in the car — turned every journey, thousands of times a year — so it wears.
The ignition switch is the electrical unit bolted to the back of the barrel. When the barrel rotates, it turns the switch, which closes the circuits for the dashboard, fuel pump and starter. When the switch fails, the key turns perfectly — but the car does nothing.
That's the whole diagnosis in one line: key won't turn = barrel (or steering lock); key turns but nothing happens = switch. Mercedes owners are the exception — most use an electronic EIS unit instead of a barrel, covered in our Mercedes EIS failure guide.
The steering lock engages when the wheel is turned after the key comes out — parking on a slope or against a kerb does it every time. The wheel's own weight then jams the lock pin against the barrel, and the key won't budge.
Put your left hand on the wheel and gently rock it left and right while turning the key with your right hand. You'll feel the wheel move a few millimetres one way — keep turning the key as it does. On automatics, also make sure the lever is fully in P.
If this frees it, nothing is wrong with the car. If it happens every week, the barrel is starting to wear and it's worth having it looked at before it fails completely.
If your spare turns the ignition and your everyday key doesn't, the problem is the key, not the car. Key blades wear down after years of use — the cuts get shallower and the pins inside the barrel stop lining up. A freshly cut key is the cheapest fix there is: key repair from £50, a new spare cut and programmed from £79.
If both keys behave the same, the barrel is the common factor — move on to Fix 3.
Key still stuck after the steering-lock trick? We repair and replace ignition barrels and switches at your location across Kent, London and the South East — no tow, no dealer wait.
A worn barrel gives itself away: the key works some mornings and not others, feels rough going in, or needs a jiggle to catch. This is the most common ignition job we attend, and it's usually cheaper than people expect.
Repair is the right call when the barrel is worn but intact — we service the pins on-site, at your driveway or roadside. Replacement is right when the barrel is seized, damaged by a theft attempt, or has a snapped key inside. Either way we pin the new or repaired barrel to your existing key, so one key still does the doors and the ignition — no second key to carry.
Both start from £150, including call-out, labour and key matching, with a 2-year warranty. For the full price breakdown see our ignition barrel replacement cost guide.
💡 Not sure whether it's the key, the barrel or the switch? A quick call to 📞 07777 676261 usually settles it in a couple of minutes — before you spend anything.
If the key rotates normally and the dashboard lights up but turning to "start" produces silence — no click, no crank — the ignition switch behind the barrel may have failed. The contacts inside wear or burn out, especially on older vans and high-mileage cars.
Before assuming the switch: a flat battery gives dim dashboard lights and a clicking starter; a failed starter motor usually gives one loud click. A failed switch gives a normal-looking dashboard and complete silence. We test all three at the car before quoting, and replace the switch on-site — from £150, all makes, cars and vans.
Ignition barrels wear on every car eventually, but these are the ones we're called to most:
If yours isn't listed, call and tell us the make, model and year — it doesn't mean we can't help.
At a main dealer, a car that won't start means recovery first (£100–£300), then a diagnostic fee, then franchise labour on a part that's often ordered in — and a quote that regularly lands between £400 and £800 for a mechanical barrel. We come to the car, confirm the fault before quoting, and in most cases fix it in the same visit. The price you hear on the phone is the price you pay.
Want a straight answer on your car? Tell us the make, model, year and exactly what the key does — we'll give you an honest assessment before any work. No dealer markup, no obligation.
1. Phone diagnosis (free). We ask what the key does — won't turn, turns but nothing, snapped — and whether the spare behaves the same. That narrows it to lock, key, barrel or switch before we set off.
2. On-site arrival. Our van carries barrel service kits, replacement barrels and switches for the common makes, key-cutting and programming equipment. We cover Kent — Dartford, Gravesend, Maidstone, Tunbridge Wells, Canterbury and Welling — plus south and west London, Essex, Surrey, Sussex, Luton via the M1, and all five London airports.
3. Diagnosis at the car. We check the steering lock, test both keys, inspect the barrel and test the switch circuit — and tell you what's wrong before any work starts.
4. Same-day fix where possible. Most barrel repairs take 30–90 minutes at your location. If a specific part needs ordering, we tell you upfront, book a return, and you pay nothing until it's done.
5. Warranty. 2 years on ignition barrel work, confirmed in writing before we begin.
6. Payment. Card, cash or bank transfer on completion. Invoiced billing for fleets.
Most often the steering lock is binding — rock the wheel while turning the key. If that doesn't free it, the key blade or the barrel pins are worn. If both your keys behave the same, it's the barrel.
On an automatic, make sure the lever is fully in Park. Then rock the steering wheel gently while easing the key out — don't yank it. If it still won't release, stop: a worn barrel is holding it, and pulling harder risks snapping the blade.
No. Oil-based sprays attract dirt and gum up the wafers, making a worn barrel worse. A small amount of dry graphite lubricant is the only thing that belongs in a lock — and if the key is already sticking, lubricant won't fix worn pins.
From £50 if it's a worn key, from £150 for barrel repair or replacement including key matching, from £150 for an ignition switch. We confirm the price before we set off.
If the key won't turn, it's the barrel (or the steering lock). If the key turns freely and the dashboard lights up but the car stays silent, it's likely the switch — though a flat battery or starter can mimic it, so we test all three on-site.
No. Barrel and switch work is done at your location — home, work, or roadside — across Kent, London and the South East, 24/7.
For related problems, see our ignition barrel repair guide for how repair actually works, our cost guide for what moves the price, or our broken key in ignition page if the blade has snapped.
If your key is stuck right now, don't keep forcing it and don't book a tow before someone has looked at it — most stuck-ignition calls we attend are fixed at the car in under an hour.
Call 07777 676261 or WhatsApp us on +44 7777 676261, 24/7. For a spare key while your current one still works — always cheaper than an emergency — use our contact form and we'll reply within the hour.
