Can We Get To You In Winchester Today?
Usually. Key jobs go into the same day's diary for most vehicles, and as your auto locksmith in Winchester, we give you a time we can keep rather than a hopeful one. Lockouts slot in around the booked work.
We're on the phones 8am–10pm on weekdays and 10am–6pm at weekends. Any car locksmith in Winchester quoting twenty minutes before asking where you are is guessing; a booked time is worth more.

Premium keys
What We're Called Out For Most In Winchester
Winchester has more than its share of premium and keyless cars, and the calls reflect it.
BMW Slot Keys And Smart Keys
Older 1 Series, 3 Series and X5 models use a slot key that recharges in the dash. One that won't hold its charge usually needs a new key rather than a battery. Newer BMWs with FEM or BDC modules are keyed at the car too, including every key lost. See BMW keys in Winchester.
Land Rover, Volvo And Audi
Land Rover's Discovery 3, and the original Range Rover Sport, need their module read on the bench once every key's lost, which takes longer but still beats a dealer trip. Volvos, including recent models, are done at the car. Older Audi A3 models share the Golf's troublesome ignition lock unit, which is a common fault on cars of that era.

Auto Locksmith Services In Winchester
Here's what our auto locksmith services in Winchester involve, job by job. For most cars, each one is a single visit.
Lost Every Key?
The lock is decoded, a blade cut in the van and a new chip programmed to the immobiliser. Lost keys are removed from the car's memory where the system allows. Full details, prices and the makes that still need a dealer are on car key replacement in Winchester.
Keys Shut Inside The Car?
Locked keys in car calls across Winchester are £95 upwards and fitted between booked jobs, usually the same day. Purpose-built entry tools mean no bent frame and no scratched paint, and car door unlocking in Winchester takes minutes once we're beside the car. More on the method: keys locked in car.
Ignition Stiff, Stuck Or Dead?
Worn barrels are rebuilt and recoded to your key where possible, or replaced where not. Honda barrels and the Golf-era ignition lock are frequent offenders. See ignition repair in Winchester.
Spares, Programming And Repairs
While one key still works, a copy costs least: spare car keys. If the car no longer accepts a key, that's car key programming. Tatty shells and dead buttons are usually a car key repair job.
Business & fleet

Their keys should too.
A lost work key affects more than one journey. Keep key replacements and spares part of your vehicle planning.

Pricing
Prices, And What To Ask Before Booking
From £95 for a lockout; everything else is quoted on the phone once we've got your registration, because a slot key for an older BMW and a smart key for a new Volvo are very different jobs.
No money changes hands until the work's done. Should the car need something you didn't describe, we explain the new price first, and turning it down costs nothing for the call-out. Keys are guaranteed for 12 months, and 450+ customers have reviewed us on Google and Checkatrade.
Whoever you ring, ask who's actually coming, because some booking lines sell the job on with a margin. Ask whether the key will start the engine, since a shop-cut blade only opens doors. And ask if the price is fixed. Any decent auto locksmiths in Winchester will answer those three straight off. Expect us to ask for photo ID and the logbook before cutting anything.
Your car. Your location. A clear next step.

Seasonal calls
December In The City
When Winchester's car parks fill up for the Christmas market and late shopping, lockouts and lost keys rise with them.
Keys dropped in a busy crowd rarely come back, and cars locked in a hurry at dusk are a December classic. Book early in the day if you can, because evening slots go fast in the run-up to Christmas.

FAQ
Winchester Auto Locksmith Questions
Will opening my car in Winchester leave any damage?
None. Car door unlocking in Winchester relies on purpose-built tools for modern locks, so the paint, seals and glass come through untouched and nothing is levered. It costs from £95, and when you're back in, the central locking and alarm work just as they did before the door shut.
Locked out in Winchester: how soon can you come?
We don't drop everything for lockouts; we fit them around the day's booked jobs, and in practice most people are back in their car the same day. Ring and you'll get a realistic time. Anyone, or any animal, trapped inside on a hot day? Dial 999 before anything else.
Do you cover the villages outside Winchester?
Yes. Kings Worthy, Twyford, the Itchen valley villages and New Alresford are routine for us as auto locksmiths in Winchester. Village jobs work the same way as city ones: the key is cut and programmed at the car, so there's no need to get it to a garage, and no long trip to a dealer.
Can you make keys for BMW and Land Rover?
Yes. BMWs are done at the car at any age, including every key lost. Land Rovers are covered too, though the Discovery 3 and the original Range Rover Sport take longer when nothing's left to copy, and the very newest models we check by registration first. Ring with your reg to confirm.
Why does my BMW slot key keep losing charge?
On older BMWs, the slot key recharges while it sits in the dash. When it stops holding that charge, it's usually the key itself that has failed, not a battery you can swap. A new key programmed to the car fixes it, and we can make one at your address in Winchester.

Where calls start
Where Do Winchester Calls Start?
Usually somewhere the car has been left for a few hours while you're busy elsewhere.
The Station And The Commute
A key that goes missing on the way to or from a London train leaves the car stuck at the station or a nearby car park. Commuters often ring in the evening, so tell us your train and we'll arrange to be at the car when you get back; that's when a car locksmith in Winchester who books around train times earns their keep. Locked keys in car problems at Winchester station are just as common, and handled the same way.
Romsey Road, The Hospital And The University
The hospital and the University of Winchester both sit off Romsey Road, and both mean cars parked for long stretches. Keys go missing on a long shift or between lectures, and being a mobile auto locksmith in Winchester, we simply come to whichever car park the car is in.

Before you ring
Locked Out Or Lost A Key? Do This First
A few minutes of checking can save you money.
Try every door and the boot, because one may still be open. Check pockets, bags and anywhere you've been. If someone nearby has a spare, that might be quickest. If not, call us with the registration and the car's location, and leave the coat hanger out of it.

Cars We Key Across Winchester
Roughly 90% of vehicles can be keyed at the car, and car locksmiths in Winchester see more premium models than most.
BMW, Audi, Mercedes-Benz, Land Rover, Jaguar, Volvo, Porsche, Volkswagen, Ford, Vauxhall, Peugeot, Citroën, Renault, Toyota, Nissan, Honda, Mazda, Kia, Hyundai.
Our work as a vehicle locksmith in Winchester involves plenty of Volkswagen, Audi and BMW, alongside everyday Ford, Vauxhall and Toyota. Where we stop: with every key gone, Volkswagens and Audis built since about 2018, and a lot of Mercedes since about 2013, are dealer work, so a spare made now is good insurance on those cars.
What customers say
450+ five-star / 10-out-of-10 reviews across Google and Checkatrade
Transit Custom Ignition Repair.
"I cannot recommend Alec enough. My transit custom lock was not turning. I did not know Alec at this point and called another locksmith. To cut a long story short the other locksmith attempted a repair and then gave up, leaving me with a van I could no longer use. I called Alec who came out next day; he repaired the damage done by the other locksmith and custom made a replacement ignition barrel so one key still does the doors and the new ignition. I couldn't be more pleased. Price was very fair too!"
Sam chapman
"Did the work at a 3rd of the price of the dealership and I'm sure to a higher quality, the work was quick and professional. Could not recommend more!"
Can work on most cars! Pricing is very reasonable! Fast reliable service!
"Absolutely spot on! After ringing about 15 different companies who said they couldn't help and one company even saying the series of my car doesn't exist I found smarttech who I contacted who could finally help! The next day he came out and I now have access and a new key to my car! Fast and efficient polite service! Highly recommend!!"
