Common Car Key Problems Solved by Auto Locksmiths in Exeter

Getting locked out, a dead key fob, or a snapped key can turn a normal day in Exeter into a stressful one — whether you’re parked by the quay, near Princesshay, or on the A30. Fortunately, auto locksmiths in Exeter and the surrounding Devon area specialise in fast, on-the-spot solutions for the full range of modern car key problems. This article explains the most common issues drivers face, how professional auto locksmiths solve them, and what you can do to minimize disruption the next time your key misbehaves.

1. Lost or misplaced car keys — fast replacement and programming

Problem: Losing your keys is the classic panic scenario. Modern cars usually require electronic programming, so you can’t simply cut a blank key and walk away.

How locksmiths solve it: Mobile auto locksmiths visiting Exeter can cut a replacement mechanical key, clone a remote key, and program transponders and smart keys on site — often without towing the vehicle to a dealer. Many local specialists advertise lost-key replacement and emergency callouts for most vehicle makes and models. For quick and dependable car key solutions, DB Car Keys stands out as a leading Auto Locksmith Exeter service.

Tip: When you still have one working key, get a spare made right away. If both keys are lost, be prepared to provide proof of ownership when the locksmith arrives. 

2. Key fob (remote) not responding — battery, signal, and internal fault fixes

Problem: Your key fob stops locking/unlocking from the usual distance, or it only works when you’re right next to the car.

How locksmiths solve it: The simplest fix is a battery replacement, which restores range and responsiveness. If a battery swap doesn’t fix it, locksmiths can diagnose antenna/signal problems or internal circuit issues. They can repair or replace the fob’s electronics and, if necessary, supply and programme a new fob. Practical troubleshooting and signal-testing are standard parts of the service.

Tip: Keep a small stock of the correct battery type for your fob in your glovebox — they’re cheap and easy to swap in seconds.

3. Transponder or immobiliser problems — reprogramming and diagnostics

Problem: You insert the key and the engine won’t start, or the car’s immobiliser refuses to recognise the key.

How locksmiths solve it: Modern keys contain transponder chips that communicate with the car’s immobiliser. Auto locksmiths use diagnostic tools and programming equipment to re-sync the transponder and ECU or to program a replacement key that the immobiliser will accept. If the immobiliser itself has an electrical fault, locksmiths can identify this and advise on next steps.

Tip: If a warning light linked to the immobiliser appears on your dashboard, don’t repeatedly crank the engine — note any error codes or messages and tell the locksmith when they arrive.

4. Broken or snapped keys — extraction and replacement

Problem: Keys wear out and can snap off in the lock or ignition — extra tricky when the broken piece is out of sight.

How locksmiths solve it: Trained technicians remove broken key fragments without damaging the lock or ignition barrel, using specialist extraction tools and techniques. Once the broken part is out, the locksmith can cut and program a replacement key. If the breakage reflects a deeper mechanical fault (for example, a worn ignition tumbler), they’ll recommend repair or replacement.

Tip: If a key shows visible wear (bent blade, worn teeth), replace it before it breaks — a small preventive expense beats being stranded.

5. Stuck or jammed locks — cleaning and mechanical repair

Problem: Door locks become stiff, jammed, or won’t turn, often due to corrosion, dirt, or freezing weather.

How locksmiths solve it: Auto locksmiths can lubricate and clean locking mechanisms, free seized tumblers, and repair or replace damaged lock cylinders. For electronic door modules that misbehave, they can perform diagnostics or bypass procedures to regain access. Their mobile kits usually include lubricants, picks, and replacement barrels if required. 

Tip: Use silicone-based lock lubricants periodically (not oil) to keep mechanisms moving freely — especially in damp Devon weather.

6. Key cutting and cloning for older or simple keys

Problem: Not every vehicle needs programming — many older models still use simple mechanical keys.

How locksmiths solve it: A locksmith can quickly and affordably cut duplicates from existing keys or original codes, and they often keep a wide selection of blanks to fit older vehicles that dealers may no longer support. This service is handy for classic cars or when you simply want a cheap spare.

Tip: Keep copies of any key codes in a safe place (or a trusted password manager) — they speed up replacement when originals are lost.

7. Smart keys and keyless entry systems — advanced programming

Problem: Push-button starts and smart key systems are convenient — until the fob fails or programming gets out of sync.

How locksmiths solve it: Many modern auto locksmiths are equipped to handle smart key reprogramming, including syncing keys to keyless entry systems and repairing the fobs’ internal electronics. They can also advise whether a new key is best or whether the vehicle needs dealer-level intervention.

Tip: If your car has multiple profiles or additional security features (geofencing, app locks), keep a note of them and tell the locksmith — it helps avoid surprises during reprogramming.

8. Emergency lockout services — fast, non-destructive entry

Problem: Locked out with the engine running or children inside, stressful and potentially dangerous.

How locksmiths solve it: Licensed auto locksmiths offer emergency callouts and aim for non-destructive entry methods: tool-assisted unlocking, bypassing electronic locks, or using strategic access points. Reputable local services emphasise speed and safety, and some operate 24/7 across Exeter and greater Devon.

Tip: Keep a list of two or three trusted local locksmith numbers in your phone and in a physical place (wallet or glovebox) so you can call quickly if needed.

Choosing the right auto locksmith in Exeter

When you need help, check that the locksmith is a legitimate, insured provider (many local firms advertise mobile, same-day service). Ask about their experience with your vehicle make, whether they can program transponders and smart keys on site, and what forms of ID they require for lost-key jobs (this is a normal security measure). Local Exeter & Devon specialists list services and emergency contact details online, a quick search will show options that come to your location.

Final checklist, what to do before the locksmith arrives

1. Gather proof of ownership (V5C, insurance documents, or ID).
   
2. Note the vehicle make, model, year, and VIN if possible.
   
3. Describe the problem clearly (lost key, broken key, fob not working).
   
4. If you have a working spare, bring it along — it can simplify the job.
   
5. Stay in a safe, well-lit place and avoid leaving children unattended.
   

Car key problems range from trivial battery swaps to complex immobiliser reprogramming. The good news for Exeter drivers is that modern auto locksmiths are equipped to handle virtually all of these issues — often at your location and usually faster and cheaper than dealer alternatives. Keep a spare, look after fobs and locks, and save a reliable locksmith’s number — that’s the best recipe for staying mobile in and around Exeter.
