When You Might Need Car Lock Or Ignition Repair
Car lock and ignition issues show up in a few common ways. If any of these sound familiar, we can help:
- Key won’t turn in the ignition

- Car key snapped in ignition or door lock
- Steering lock won’t release

What’s Causing The Problem?
Understanding the root cause helps avoid repeat failures. Typical sources include:
- Worn or damaged lock wafers and ignition barrels after years of use
- Misaligned or bent key blades, especially with laser cut car keys
- Debris, corrosion, or lack of lubrication inside locks and barrels
- Faulty ignition switch electronics or immobiliser ring (transponder reader)
- Steering lock mechanism failure or column lock jam
- Broken or worn key blades causing poor engagement
- Central locking actuator or linkage failure in the door
- Faulty or water-damaged key fob, dead battery, or fob needing reprogramming
- Immobiliser or ECU sync issues after battery changes or jump starts

How We Compare To The Dealer

For an estimate tailored to your vehicle and fault, see our guidance on auto locksmith prices in Harrow.
Preventing Future Lock And Ignition Problems
A few simple habits help prolong the life of locks and ignition components:
- Avoid heavy keyrings that strain the ignition switch
- Replace tired or bent keys; don’t force a key that sticks
- Keep fob batteries fresh; intermittent locking can stress mechanisms
- Use a light, appropriate lubricant on door locks (never overdo it)
- Address central locking glitches early before actuators fail
- After a flat battery, if you see a key symbol or “not detected”, call for advice before repeated attempts
If your fob has gone intermittent or won’t respond, see our guide to key fob not working.

FAQs
Can you fix an ignition that won’t turn without replacing it?
Often, yes. Many ignitions fail due to worn wafers or a worn key. We can refurbish or replace the barrel, cut a fresh key to code, and adjust the ignition switch as needed. We only replace the unit when repair isn’t reliable.
My steering lock is stuck. Can you help?
Yes. We diagnose whether it’s a mechanical column lock, electronic steering lock, or immobiliser-related issue. Depending on the vehicle (e.g., Mercedes, VW, BMW), we can repair or replace components and reprogram if required.
The key is stuck in the ignition. Will you have to drill it?
In most cases, no. We use specialist extraction tools and techniques to remove a stuck or broken key non-destructively. If drilling is the only safe option, we’ll discuss it first and replace the damaged component.
Central locking isn’t working on one door. Is that a big job?
It’s usually an actuator or linkage issue. We can replace the faulty actuator and ensure the linkage operates smoothly. We’ll also check the wiring for broken door loom cables, which are a common cause on some models.
My key symbol is flashing on the dashboard and the car won’t start. Is this the immobiliser?
Likely, yes. It may be a transponder chip or antenna ring issue, a key sync problem after a battery change, or ECU/immobiliser communication fault. We can run OBD2 diagnostics, resynchronise keys, and repair or program modules as needed.
How long does a lock or ignition repair take?
Many repairs are completed on-site in one visit. Timing depends on the vehicle and fault complexity. We’ll provide a realistic timeframe after diagnosis and keep you informed throughout.
Will my warranty cover this work?
We provide our own warranty on workmanship and keys. Manufacturer warranties vary; we’ll explain how our repair interacts with your vehicle’s warranty and provide an invoice and documentation.
