If you drive in Exeter — whether you’re parked near Princesshay, commuting through Marsh Barton, or heading out from Heavitree — one thing every motorist dreads is a lock-related problem. Thankfully, local auto locksmiths in Exeter carry the tools, training, and mobile workshops needed to get you back on the road quickly and without the heavy price-tag often quoted by dealerships. Below is a practical, user-friendly guide to the most common vehicle lock issues they deal with, what causes them, and how an experienced Exeter auto locksmith can fix them.
- Locked out — keys left inside or lost keys
One of the top callouts for auto locksmiths is the classic lockout: keys locked inside the car or an only set of keys misplaced. Instead of smashing a window or waiting for a tow, a mobile vehicle locksmith will use non-damaging entry techniques (slim-jims, inflatable wedges combined with long-reach tools, or electronic unlocking tools on modern cars) to open the door and retrieve or assist with replacing keys. Many Exeter-based locksmiths advertise rapid, 24/7 response for this exact scenario. Auto Locksmith Exeter assistance through DB Car Keys ensures drivers receive professional help for urgent car key and access issues.
Why use a locksmith: quicker, usually cheaper and less damaging than breaking in or going through a dealer.
- Broken, snapped, or worn keys (including key stuck in ignition)
Metal keys can wear down or snap — sometimes the fragile part of a modern high-security or laser-cut key breaks off inside the lock or ignition barrel. Locksmiths carry extraction tools to remove broken key fragments safely, and mobile key-cutting equipment to produce replacements on the spot if required. They can also cut and code replacement keys for most makes and models without towing your car to a garage.
Quick tip: If your key feels gritty or unusually loose, get a spare cut sooner rather than later — it’s cheaper than emergency replacement after a snap.
- Faulty or dead key fobs and remote locking problems
Modern cars rely heavily on electronic key fobs and remote systems. Common issues include flat batteries, damaged contacts, or internal circuit faults (sometimes worsened by heat or moisture). Locksmiths can usually replace fob batteries, repair fob housings, and — importantly — reprogram or replace fobs and transponder keys at roadside using diagnostic and programming tools. This avoids dealership delays and costs in many cases. Recent reports even highlight how environmental factors (like overheating) can damage fobs, creating sudden access problems — something locksmiths are equipped to diagnose and fix.
Practical advice: keep a small pack of replacement batteries and an old spare fob (if you have one) at home.
- Transponder and immobiliser programming issues
If your car uses a transponder chip (an immobiliser) and that chip becomes de-synchronised, your vehicle might not start even though the mechanical key turns in the ignition. Auto locksmiths can read or clone transponder chips and program new keys so they communicate correctly with your vehicle’s immobiliser system. Many mobile workshops in Devon and Exeter are equipped to program keys for a vast range of makes and models on-site.
Why it matters: Immobiliser faults can be misdiagnosed as starter or battery problems; a locksmith can rule in/out immobiliser issues quickly.
- Jammed, sticky, or worn door locks and mechanisms
Locks that are sticky, hard to turn, or that intermittently refuse to operate typically suffer from wear, corrosion, or foreign objects in the mechanism (dirt, grit, or a fragment of a broken key). Locksmiths can clean, lubricate, repair, or replace door lock cylinders and internal mechanisms — often without removing the entire door trim — restoring smooth operation. For older cars, replacing a worn cylinder with a new one is often the most cost-effective long-term fix.
Maintenance tip: lubricate locks with a graphite-based lubricant (not oil) to reduce wear and grime build-up.
- Ignition barrel problems and replacements
If the key won’t turn in the ignition, or turns loosely without engaging, the ignition barrel (also called the ignition cylinder) may be damaged or worn. Locksmiths can remove, repair, or replace ignition barrels. They can also change the vehicle’s keys to match a new barrel so you don’t end up with mismatched keys. Mobile units carry cylinder replacements for many common vehicles and can perform this work at home or roadside.
Warning sign: difficulty turning the key, or the key popping out — don’t force it; call a professional to avoid breaking the key.
- Central locking and actuator failures
Central locking relies on actuators and wiring in each door. Symptoms of actuator failure include doors that won’t lock/unlock from the remote or button, or unusual noises when the system operates. Locksmiths can diagnose wiring and actuator problems and replace door actuators or faulty modules. In many cases they’ll test electrical circuits, replace the broken actuator, and reprogramme the central locking so everything works smoothly again.
Good to know: Some central locking repairs require removing the interior door card — a locksmith with experience will refit everything neatly.
- Immobiliser/key recognition errors after battery disconnects or vehicle servicing
Sometimes, after a battery replacement or certain types of servicing, a vehicle’s key recognition can fail and the car may not accept previously working keys. Auto locksmiths can diagnose whether the problem is key-related or ECU-related and re-sync keys or recommend the appropriate diagnostic route (programming vs dealer ECU work). Mobile locksmiths frequently handle these re-synchronisation tasks on-site.
- Emergency extraction of keys from locks or ignitions
If a key has snapped in a lock or ignition, the locksmith’s first job is to extract the remaining fragment without damaging the mechanism. Trained technicians use specialised extractors and microscopes where required. Once removed, they can make a replacement key and, if necessary, repair any damage the fragment caused. Devon specialists emphasise roadside extraction and replacement as a common and essential service.
- Replacing lost keys, supplying spares, and security advice
Lost your only key? A reputable locksmith can supply and program a replacement — sometimes cheaper and faster than going to the dealer. They’ll often recommend and supply spare keys, advise on secure storage, and, if keys were stolen, offer re-keying or immobiliser changes to protect against theft. Many Exeter locksmiths advertise mobile cutting and programming for immediate spare key creation.
Security note: If your keys were definitely stolen, consider re-keying or immobiliser changes — the locksmith can advise on the level of risk and appropriate action.
Choosing a reliable auto locksmith in Exeter — what to check
- 24/7 mobile response — many Exeter locksmiths offer mobile callouts and 24/7 help; check their advertised coverage.
- Memberships and accreditation — look for Master Locksmiths Association (MLA) membership or similar credentials.
- Transparent pricing and quoted estimates — reputable locksmiths will give a clear call-out fee and estimate before work begins (and will avoid “surprise” dealer-level charges).
- On-site programming and mobile workshop — if you need a transponder or key fob programmed, confirm the locksmith has mobile programming capability.
- Good local reviews and clear ID — ask for an ID, vehicle registration, and check online reviews (local trade directories like Checkatrade can be useful).
Final practical tips for Exeter drivers
- Keep at least one spare key in a safe place (not inside your vehicle).
- Don’t force a sticking key; forcing often causes breakage.
- Replace key fob batteries as part of routine checks and avoid exposing fobs to extreme heat.
- If you’re stranded, call a verified local auto locksmith — they often beat dealer turnaround times and prices.
