MG key replacement in Liverpool
ADC Locksmith Liverpool replaces, repairs and programs MG keys at the car across Liverpool and Merseyside, from an MG3 flip key to a keyless MG4 or HS smart key. Craig checks the key system from the registration, agrees the full cost before travelling and tests the start before handover. Replacement keys start from £120, and the exact MG price depends on the key type and whether a working key remains. A spare MG key commonly takes 20 to 40 minutes at the car, and an all keys lost key 45 to 90 minutes.
MG key service at a glance
Four answers MG owners need first
Most MG calls start with the same four questions, so the answers sit here before the technical detail.
ADC replacement keys start from £120. A spare MG key commonly costs £95 to £180 with a mobile independent, a new MG key with every key lost £180 to £350, and a main dealer often charges £250 to £500. Craig fixes the exact price from the registration before travel.
Add a spare while a working key remains, repair a flip key whose circuit still works and use a mobile independent instead of the main dealer. An all keys lost job on a smart key model costs the most.
Yes. Every MG key carries a transponder chip or a smart key code that the car checks before the engine starts. Newer MG models need a security code route before a key can be added, and Craig checks that route from the registration.
The registration, the location, whether any working key remains and whether the car starts with a key or a button. A photo of the old key helps too.
The key type sets the MG job
An MG key is a transponder key or a smart key, and the car checks its code before the engine or the electric drive starts. Newer MG models need a security code route before a key can be added, and Craig checks that route from the registration.
Many MG cars are sold on finance or lease with a single key from the first owner, so adding a second key is the most common MG job.
MG has used three main key types, and the key type decides the programming route, the time and the price.
- Flip keyA folding blade with three buttons on the MG3 and earlier ZS and HS models.
- Smart keyA push start fob with an emergency blade inside, on newer ZS, HS, MG4, MG5 and Marvel R models.
- Remote keyAn older remote key on the MG6 and GS.
What Craig checks before programming
- Registration, model and model year
- Flip key or smart key
- Security code route on newer models
- Whether any working key remains
- What the dashboard shows at start
- Proof of ownership before security work
The method comes from the registration and the key type, never from the badge alone.
MG key replacement cost in the UK
ADC replacement keys start from £120. The MG price depends on the key type, the programming route and whether a working key remains, and a worn key often needs a repair rather than a new key. Craig fixes the price after checking the registration.
MG spare keys start from about £95 and all keys lost jobs from about £180 with mobile independents. A flat battery or a worn case costs less than any figure in the table.
Cheapest route to a new key
- Repair a worn key when the circuit still works
- Add a spare while a working key remains
- Use a mobile independent instead of the dealer
- Skip online keys that do not match the car
Key and car factors
- Flip key or smart key
- Security code route on newer models
- Model, year and fuel type
- Whether a repair solves the fault
Situation factors
- Spare key with a working key present
- All keys lost with no reference key
- Location and access to the car
- Out of hours call out
The registration gets a fixed quote. Tell Craig the registration, whether any key still works and what happened. The price is agreed before travel, with no call out surprise at the car. For the general service, see car key replacement in Liverpool.
The symptom points to the right fix
A worn MG flip key, an MG that does not see the smart key and an MG that does not start are three different jobs.
Smart key not detected on the dash
A flat fob battery is the usual cause. Holding the smart key close to the start button area lets most MG models read the key and start.
Flip key blade loose or case split
A worn hinge or a split case stops the blade locking open. A new case moves the working circuit across, so the key keeps the same programming.
Remote stops after a battery change
A coin cell fitted the wrong way round, a weak cell or a worn button contact stops the remote. A battery change keeps the key paired to the car.
Only MG key lost or stolen
With no working key, the car becomes the reference. Craig checks the key type and the programming route first, because those decide the method and the price.
Blade snapped or badly worn
A snapped or worn blade often leaves the circuit healthy. A new blade and case save the cost of a full key.
Second key needed before an emergency
A spare is the cheapest MG key job because the working key helps with programming and testing.
Check compatibility first. A used or online MG key that looks right is often locked to its previous car or carries the wrong chip, so send the registration before buying one.
Every MG key tested before handover
A new MG key leaves the van only after the start, the locks and the remote pass a test. A spare commonly takes 20 to 40 minutes and an all keys lost key 45 to 90 minutes, against one or more days through a main dealer.
Programmed, cut and tested at the car
Craig reads the car, programs the new key, cuts the blade in the van and tests the start, the central locking and the remote buttons with you at the car.
A lost key comes out of use at the same visit wherever the system allows, so a found or stolen key no longer starts the engine.
An electric MG smart key is tested with the car in ready mode, so the handover covers the start, the locks and the remote together.
MG models covered across Merseyside
MG changed key types between generations, so the registration confirms the exact key before a quote.
MG cars and SUVs
Typical calls cover MG3 and ZS flip keys, plus ZS and HS owners with smart keys around Liverpool and the Wirral.
Electric MG models
Electric MG models use smart keys, so the model year decides the programming route and the price.
For an import, an older model or a model not listed, call anyway. The answer depends on the registration and the key type.
How Craig handles every lost MG key
An all keys lost MG job is a new key made with no working key present, so the car itself becomes the reference for the new key.
Vehicle identified from the registration
The registration gives the model, the year and the key type, which decide whether the key can be made at the car.
Ownership confirmed before security work
Craig asks for the V5C or other proof of ownership plus photo ID before any key is programmed. This check protects you and the car.
Security data read from the car
On supported models, the data the new key needs comes from the car itself, so no working key is required.
New key programmed and blade cut
The new key is programmed to the car and the blade is cut to match the door lock.
Start, locks and remote tested
The engine start, the central locking and the remote buttons are tested before the job ends.
Dealer route explained when needed
Where a newer MG needs a code or a key the car cannot accept at the roadside, Craig explains the dealer route and the timing before any charge.
Why a spare costs less
A spare key job starts with a working key that the car already trusts. An all keys lost job starts with nothing, so the car becomes the reference and the work takes longer.
A dealer lost key job often needs the car at the workshop and a key ordered in, which adds recovery and waiting days. For supported models, Craig brings the equipment to the car instead.
Mobile locksmith, main dealer or online key
An MG key comes from a mobile auto locksmith, a main dealer or an online blank key that still needs cutting and programming.
All three routes need proof of ownership and end with a key programmed to the immobiliser of the car. The difference is where the work happens and how long the car stands.
Many faulty MG keys need repairs only
The cheapest outcome is the smallest repair that fixes the fault for good. Craig separates battery, case, blade and programming faults before recommending a new key.
From registration to a working MG key
Share the MG and the problem
Send the registration, your location and whether any working key remains. A photo of the old key helps when one exists.
Craig checks the key system
Craig identifies the key type and the programming route, then confirms the job suits a mobile visit.
Ownership is confirmed
Security work needs proof that you own the car or have authority to request the key.
Program, cut and test
The key is programmed, the blade is cut and the start, the locks and the remote are tested before the job ends.
Why mobile matters. A dealer lost key job often starts with a tow and a wait for a key ordered in. For supported models, Craig completes the job where the car stands, so there is no recovery bill.

MG key questions answered before booking
The answers below cover the MG questions that decide the route, from used keys to repairs.
Where is the MG back up mechanical key?
Inside the smart key. A release button frees the emergency blade, which opens the driver door when the fob battery is flat.
The car then reads the fob at the start button.
Do electric MG models use a different key?
They use the same smart key design as the petrol ZS and HS, with the electric drive checking the key.
The model year decides the route and the price.
MG and Dacia keys priced side by side
MG and Dacia sit at the value end of the UK market, and both often leave the first owner with one key. A Dacia key commonly costs a little more than an MG flip key. For Dacia models, see Dacia key replacement.
Repair a worn MG key before replacing it
Worn buttons, a split case or a flat battery often need a repair only, at a fraction of a new key. See key fob repairs.
Spare MG key against all keys lost
A spare MG key costs less and takes less time, because the working key helps with programming. See spare car keys.

Questions MG owners ask before booking
How much does a replacement MG key cost in the UK?
ADC replacement keys start from £120. A spare MG key commonly costs £95 to £180 with a mobile independent, a new MG key with every key lost £180 to £350, and a main dealer often charges £250 to £500. Craig fixes the exact price from the registration before travel.
How much is an MG ZS replacement key?
A spare ZS key with a working key present commonly costs £95 to £180 with a mobile independent, and a ZS smart key with every key lost £180 to £350. Craig fixes the exact price from the registration.
Why does my MG say key not detected?
A weak smart key battery is the usual cause, followed by a damaged fob or interference from another key or phone nearby. Craig tests the key and the car before replacing anything.
How do you start an MG with a dead smart key?
Open the driver door with the emergency blade inside the fob, then hold the smart key close to the start button area and press it. The car reads the key at close range.
Do you cover electric MG models?
Yes, for supported models. MG4, MG5 and ZS EV smart keys are checked from the registration first, because the model year decides the route.
Can you replace an MG key if every key is lost?
Yes, for supported models. Craig checks the key type and the programming route from the registration first. Where the car needs a dealer key, Craig explains that before any charge.
How long does a new MG key take?
A spare, a repair or a supported all keys lost job is usually finished at the car in one visit. A key ordered through a dealer commonly takes several working days.
Does changing the fob battery erase the programming?
No. An MG key stays paired to the car after a battery change. If the remote still fails with a fresh coin cell, the circuit, the buttons or the pairing need checking.
Can you make a spare MG key while I still have one?
Yes. A spare is the simplest and cheapest MG key job, because the working key helps with identification and testing.
Do I have to tow my MG to a dealer?
Not for supported models. Craig attends the car with the programming and cutting equipment, so the key is made where the car is parked.
How much does a genuine MG key replacement cost?
A main dealer commonly charges £250 to £500 depending on the model and the key type.
