When You Might Need Car Lock Or Ignition Repair

Car lock and ignition problems can appear suddenly or get worse over time. Common symptoms include:

• Key won’t turn in the ignition or barrel feels rough or jammed
• Key stuck in ignition and won’t remove without force
• Car starts intermittently or cuts out due to ignition switch faults
• Broken ignition key extraction needed after a key snaps in the barrel
• Steering lock issues (ESL/ELV fault) preventing the car from starting
• Central locking not working on one door, or remote unlock only works sometimes
• Deadlocks or boot lock jammed; door latch or lock actuator not responding
• Immobiliser/key symbol on the dashboard; “Key not detected” on push‑to‑start cars
• Worn or damaged keys that no longer operate locks or ignition reliably
• Vehicle lock malfunction after attempted theft or weather-related wear

If any of these sound familiar and you’re in the N postcode area, we can help with fast, mobile diagnostics and repair.

What We Can Do To Fix It

We’re set up to resolve everything from simple mechanical wear to complex electronic faults. Our approach:

• Expert diagnosis on-site

  • We use dealer‑level equipment and OBD2 diagnostics to read fault codes, test live data and pinpoint issues across door modules, body control modules (BCM/BSI), immobiliser systems and ignition switches.
  • Where required on certain models, we perform EEPROM work to repair or adapt immobiliser data, keys and modules.

• Non-destructive entry and careful repairs

  • We prioritise non-destructive techniques to protect your vehicle. If a destructive method is the only safe option (for example, a heavily damaged lock or seized component), we explain it clearly first and replace parts like‑for‑like.

• Ignition barrels, switches and steering locks

  • Repair or replacement of worn ignition barrels and wafer/tumbler packs.
  • Ignition switch testing and replacement for intermittent starting faults.
  • Steering lock repair for systems such as Mercedes ESL/ELV, BMW ELV and other electronic column locks.

• Lock, latch and actuator issues

  • Door and boot lock repairs, including rekeying to match your existing key.
  • Central locking problems diagnosed; replacement of faulty door lock modules/actuators and microswitch repairs on many models.
  • Vehicle lock malfunction repair after attempted theft or water ingress.

• Immobiliser and key programming

  • If a transponder or smart key is part of the problem, we can cut and code new keys and fobs, and synchronise immobiliser systems.
  • We support transponder key programming, smart/proximity keys and remote central locking.

• Key repair and replacement support

  • Worn or bent key blades replaced; flip key repair and key blade replacement available.
  • If your key snapped in the lock or ignition, we provide broken ignition key extraction and can produce a new key if needed.

If your issue involves the remote or electronic side of things, see our dedicated page for car key programming. If you’re locked out, we can help you back into the car with safe, non‑destructive methods – see our vehicle unlocking service. For remote or fob faults, our guide to key fob not working explains the common causes and fixes.

Our Simple, Mobile Process

• 1. Friendly triage
  • Tell us what’s happening: symptoms, vehicle make, model, year, and your location in North London. Photos and a short video can help us identify the likely fault faster.
• 2. Rapid dispatch
  • We schedule a mobile technician to come to you across N postcodes (Islington N1, East Finchley N2, Finchley Central N3, Finsbury Park N4, Highbury N5, Highgate N6, Holloway N7, Crouch End N8, Tottenham N17, Wood Green N22 and beyond).
• 3. On‑site diagnosis
  • We test the mechanical lock parts, electrical connections, ignition switch and modules with dealer‑level diagnostics (OBD2) to isolate the problem accurately.
• 4. Repair and test
  • We carry common locks, ignition parts and programming tools on our vans, enabling same‑day repairs in most cases. Every job is tested thoroughly (mechanical function, remote central locking, immobiliser recognition, and starting).
• 5. Handover and warranty
  • We explain what we fixed, any parts replaced and aftercare tips. Our workmanship and new keys/parts are covered by warranty for your peace of mind.

Costs And Quotes

Every car lock and ignition repair is different. Pricing depends on:

• Vehicle make, model and year
• Whether the fault is mechanical (barrel/lock) or electronic (switch, module, immobiliser)
• The presence of a working key or need for a replacement
• Parts availability and whether coding/programming is required
• Timing and location (standard call vs urgent roadside assistance)

We don’t publish fixed prices because these factors vary from job to job, but we’re happy to give an accurate estimate once we know the details. For more detail on how pricing works, see our page on auto locksmith prices North London.

Safety And Non-Destructive Methods

Your vehicle’s integrity matters. We use non‑destructive entry and repair techniques wherever possible. If parts are seized, broken or have been damaged by an attempted theft, force may be unavoidable to remove a failed component safely. In those rare cases:

• We explain the options and costs clearly before work begins
• We use manufacturer‑appropriate methods and tools to minimise cosmetic impact
• We replace removed parts like‑for‑like and test thoroughly

FAQs

What should I do if my key is stuck in the ignition?

Do not force it. Turning harder can snap the key, complicating the repair. Put the car in park/neutral and check the steering wheel isn’t under tension. If it’s still stuck, we can carry out safe broken ignition key extraction and assess whether the barrel needs repair or replacement.

Why won’t my car key turn in the ignition?

Common causes include worn key blades, damaged wafers/tumblers in the barrel, a failing ignition switch, or a steering lock fault. Cold weather and dirt can also aggravate wear. We’ll test the key, inspect the barrel and, if needed, check the switch and steering lock electronically to find the exact cause.

My car won’t start and there’s a key symbol on the dash – what does it mean?

That usually points to an immobiliser issue. It may be a transponder/key fault, an antenna/reader problem, or a control module error. We use OBD2 diagnostics and, where appropriate, EEPROM/immobiliser programming to restore key authorisation or code a new key.

Central locking isn’t working on one door – can you fix it?

Yes. That’s often a door lock module or actuator fault, but can also be a wiring or microswitch issue. We can test the door, supply and fit a replacement module where needed, and re‑synchronise the central locking system. If your remote’s the issue, see our guide to key fob not working.

Can you repair my ignition on-site the same day?

In many cases, yes. Our vans carry common ignition barrels, switches and programming tools. Some vehicles require parts to be ordered or specialist EEPROM work; if so, we’ll secure the car and complete the repair as soon as parts arrive.

Will you damage my car during repair?

Our default is non‑destructive entry and repair. If a component is already failed or seized and must be drilled or removed, we’ll explain why, agree the plan with you, and replace it like‑for‑like. We treat your vehicle with care at every step.

How much will it cost?

Costs depend on the vehicle and fault. After a quick call with your registration and symptoms, we’ll provide a free, no‑obligation estimate. For an overview of cost factors, visit auto locksmith prices North London.
