Your car
Nine times out of ten, yes, and your registration settles it before anyone sets off. Replacement car keys in Eastleigh, keyless and push-button models included, are programmed at the car for most makes.
A Ford built up to 2023, a Vauxhall or Peugeot of any age, a BMW whatever the year, a Toyota hybrid: all are made at the car. The limits are worth knowing upfront. A Volkswagen or Audi from about 2018 on, with every key gone, goes to the dealer, as do many Mercedes-Benz built after about 2013. Plenty of 2018-on Kias only accept a genuine Kia key, priced from around £350 before it's programmed.

Areas we cover
Before you call
Two minutes of checking can save you money, and one question can save you a lot of hassle.
Check coat pockets, the gym bag and anyone who might hold a spare, and ring the last shop or café you visited. If you think the key was stolen rather than dropped, report it and tell us when you call, because that changes how we deal with the old key.
Plenty of national names and booking sites are middlemen who pass the job to whoever's free and keep a cut. A high-street shop offering car key cutting in Eastleigh can copy a blade from a key you've still got, but it won't program the chip, so the car still won't start. Ask who's coming and whether the key will start the engine before you agree to anything.
One visit
The blade and the chip are two separate jobs, and we do both at the car.
With no key to copy, a decoder reads the driver's lock and the blade is cut in the van to match, so lost car key replacement in Eastleigh never needs the original. Car key cutting in Eastleigh this way handles laser-cut profiles as well as older edge-cut keys.
Then the chip is introduced to the immobiliser, the remote is paired and, on keyless cars, walk-up entry is set up. Car key programming in Eastleigh also lets us cancel the missing key in the car's security system where that's possible, so a finder can't drive off.

Pricing
Three things set the car key replacement cost in Eastleigh: the type of key, how the car's security accepts new ones, and whether a working key survives. We quote from your reg before travelling, and nothing is paid upfront.
An all-keys-lost job takes more work than copying a spare, so it costs more. Every price is given before anything is taken apart; if one symptom could be more than one fault, you hear each possible price on the phone first, then we confirm at the vehicle. Keys are guaranteed for 12 months, and you can see what 450+ customers said on Google and Checkatrade before booking.

Local
Lost car keys in Eastleigh tend to vanish on dog walks, school runs and the walk back from work. The car is usually somewhere awkward when it happens, which is the point of a mobile service.
Keys dropped on the paths at Itchen Valley Country Park, on the edge of West End, are a regular call, as are driveways in Hiltingbury after a frantic morning search, and works car parks off the A335. Mobile car key replacement in Eastleigh brings the van to wherever the car is sitting.

FAQ
Often, yes. If the electronics still work and only the case has split or the buttons have worn through, a replacement key fob in Eastleigh can be a new shell around the old insides. If the remote itself has died, we supply and pair a new one. Some keyless fobs, Honda's for example, must match the original part number exactly.
Usually, yes. Once the replacement exists, a second key is copied from it rather than built from scratch, so spare car keys in Eastleigh made on the same visit cost far less than another all-keys-lost job later. Two-car households and anyone sharing a car with a learner tend to find it pays for itself quickly.
On most cars it's struck off the list of accepted keys when the new one is coded, so it can't start the engine. The door lock is mechanical, though, and deleting a key doesn't alter it, so the lost blade may still open a door. If your address went missing with it, mention that on the call and we'll go through what's possible for your car.
Yes. We need photo ID with either the V5C logbook or, for a financed car, the finance paperwork. Lease and company cars need written permission from the owner. Owners of 2019-on Vauxhall, Peugeot and Citroën models need it twice over, because adding a key there needs a security PIN purchased from the manufacturer with your ownership details.
For most cars, just the length of the visit, because the key is made on the spot rather than ordered in. A spare copied from a working key is the quickest job; an all-keys-lost key takes longer, and some premium cars longer again. We'll estimate the time on the call.

What customers say
"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!"
"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!"
"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!!"
