Auto Locksmith Hertfordshire | 24/7 Car Keys & Lockouts

Back at the car at South Mimms services with a fob that will not respond, or standing in the Brookfield car park in Cheshunt holding a key that has stopped turning. A lot of Hertfordshire's key problems happen on the roads that run through it, and they are fixable wherever the car is sitting.

We are Hunter Locksmiths, an auto locksmith covering Hertfordshire. The A10 runs straight up through Waltham Cross, Cheshunt, Broxbourne and Hoddesdon and on towards Hertford, while the M25, the M1 and the A1(M) take in Watford, Potters Bar, Borehamwood, Hatfield and St Albans.

Car and van keys are our main job rather than a sideline. Lost keys, ignition faults, immobiliser problems and vehicles that will not open are what our vans carry the kit for, every day of the year and at any hour.

Where Hertfordshire Keeps Us Busy

Plenty of Hertfordshire’s key problems happen on the move. South Mimms services sits where the M25 meets the A1(M), and it is a common place to lock the keys in or come back to a fob that has given up. The A1(M) through Hatfield and Welwyn Garden City is the same story further north.

Then there are the commuter stations. St Albans City, Welwyn Garden City, Hatfield and Potters Bar all fill their car parks with cars that sit for ten hours while their owners are in London. That is long enough for a weak fob battery to die, or for an ignition fault to finally strand you. Getting back off the train to a car that will not start does not have to mean a recovery truck. More often it means a replacement car key or a proper diagnosis at the car.

Shopping and days out account for plenty too. The Galleria in Hatfield, Brookfield Shopping Park in Cheshunt, Paradise Wildlife Park near Broxbourne and the River Lee Country Park paths are all places keys get dropped, locked in or lost.

Van Work Across the County

Hertfordshire has a lot of trades working out of vans, from the business parks around Cheshunt and the M25 to the industrial estates in Hoddesdon and Hatfield. A van that will not open on a Monday morning is a day of lost work, which is why we carry the blanks and programming kit to sort van keys on the spot rather than ordering parts and coming back.

If you are right on the London border in Cheshunt or Potters Bar, our North London coverage is just down the road as well. Heading east towards Harlow, we cover Essex too.

The Calls We Get Most

Lost Car Keys

Keys lost at South Mimms services, in the station car parks at St Albans and Welwyn Garden City, at The Galleria in Hatfield or along the River Lee paths. We cut and program replacement keys at the car for almost every make and model, including transponder keys, remote fobs and proximity keys. You do not need the original, and the car does not need to go to a dealer.

Ignition Faults and Keys That Will Not Turn

If the key goes in but will not turn, the ignition barrel is usually the problem rather than the key. We diagnose and repair ignition faults where the car is parked, which saves recovering it to a garage. Barrels rarely fail without warning, so a key that has been getting stiff is worth a call before it strands you.

Immobiliser and Keyless Entry Problems

Keyless cars are easier to live with and easier to take, and relay theft is not only a London problem. We handle immobiliser faults, failed fob programming and keyless systems that have stopped recognising a key that worked yesterday. If the car turns over and will not start, that usually points here rather than at the engine.

Locked Out of Your Vehicle

Keys shut inside, a key snapped in the door, or central locking that has stopped working. We open vehicles without damage, and we do not drill unless there is genuinely no other way. If it ever comes to that, we explain why before we start.

Van Keys and Van Security

Trades across Hertfordshire run on vans. We cut and program van keys for all the common makes, and fit deadlocks, slam locks and extra security for anyone leaving tools in the vehicle overnight.

How Quickly We Reach You

Waltham Cross, Cheshunt, Broxbourne, Hoddesdon, Hertford, Potters Bar, Borehamwood, Hatfield, St Albans and Watford all sit on the A10, the A1(M), the M1 or the M25, which is how we get across the county quickly.

How long we take depends on where you are and what the M25 is doing at the time, so we would rather give you a real answer on the phone than put a number on a website. Ring us and we will tell you honestly how long we will be, and stick to it.

If we cannot get to you quickly, we will say so rather than leave you waiting.

Frequently Asked Questions

Which parts of Hertfordshire do you cover?

The southern side of the county, including Waltham Cross, Cheshunt, Broxbourne, Hoddesdon, Hertford, Hatfield, Welwyn Garden City, St Albans, Watford, Potters Bar and Borehamwood. If you are not sure whether we reach you, ring and ask, it takes ten seconds.

I am at South Mimms services with a key problem. Can you come out?

Yes. Service station car parks are a regular callout. Tell us where you are parked when you ring and we will come to the car. If you are on the hard shoulder rather than in the services, get somewhere safe first and ring from there.

How much does a replacement car key cost in Hertfordshire?

It depends on the make, model and year, because keys and programming differ between vehicles. Ring us with your registration and we will price it on the phone before we set off. Nothing is added afterwards.

Can you make a new key if I have lost all of mine?

Yes. We do not need an existing key. We can generate and program a new one to the vehicle for almost every common make.

My car is at St Albans station and the fob has stopped working. Can you help?

Yes, commuter car parks are one of our most common calls. A fob that worked in the morning and not in the evening is usually a battery or a programming fault, and both can be sorted at the car.

The key turns but the car will not start. Is that a locksmith job?

Often, yes. That usually points to the immobiliser or the key programming rather than the engine. It is worth ringing us before you pay for recovery.

Do you come out at night in Hertfordshire?

Yes, 24 hours a day, 7 days a week, including bank holidays.

Do you do van keys and van security?

Yes. Van key replacement and programming, plus deadlocks, slam locks and extra security for trades across the county.

Will you damage the car getting in?

No. We open vehicles without damage as standard. Drilling is a last resort, and we would explain why before doing anything.

Is there a call out fee on top of the price?

No. The price we give you on the phone is the price you pay, with no hidden fees.
