Audi Key Replacement Worthing With Keys Coded at Your Car
Audi key replacement is a new flip key or keyless key cut and coded to your Audi, so it opens, locks and starts the car. Worthing Auto Locksmith does it at the car on the A3, A4, Q3, Q5 and most other models, and tells you on the call if your Audi is a newer MLB car that needs a working key or the dealer.
Audi Key Replacement in Worthing
Every Audi from the mid 1990s has a factory immobiliser, so a new key has to be cut to the lock and coded to the car before it will start. Audi stopped releasing key security data to the trade years ago, so the data is read from the car itself. The platform your Audi is built on decides how that is done and who can do it. For other makes, see the car makes we cover.
Spare Audi Keys When One Key Still Works
With a working key, a second key is coded alongside it. It is the cheapest route on every Audi and the only easy route on MLB cars, so it is worth having before the last key goes. The wider service is a spare car key.
MQB, BCM2 and MLB, the Key System in Your Audi
Audi uses different immobiliser platforms across its range. The model and year point to the platform, and the platform decides what can be done at the car.
| System | Typical Audi models | Spare key | All keys lost |
|---|---|---|---|
| IMMO 4 | A3 8P to about 2012, TT 8J | At the car | At the car |
| MQB | A3 8V from 2013 to 2020 | At the car | At the car |
| BCM2, earlier cars | A4 B8 to 2012, A5 to 2016, Q5 to 2012, A6 C7 to 2013 | At the car | At the car |
| BCM2, later cars | A4 B8 from 2013, Q5 from 2013, A6 C7 from 2013 | At the car | Needs online access, confirmed on the call |
| MLB | A4 B9 from 2016, A5 from 2016, Q5 from 2017, A6 C8, Q7, Q8 | With a working key | Very limited, usually the dealer |
If your Audi needs the dealer, you are told on the call, before anyone sets off, so you never pay for a visit that cannot finish.
Audi Key Types
The key in your hand says a lot about the car behind it.
Audi Flip Remote Keys
The folding key with lock, unlock and boot buttons. It carries the blade, the chip and the remote, and is the key on most A3, A4 B8, Q3 and Q5 cars built before the MLB platform.
Audi Advanced Key
The keyless option that opens and starts the car from your pocket. It is coded to the keyless system as well as the immobiliser, which is the work described under smart key replacement.
The MLB Key
The newer, flatter key on MLB cars, with a hidden emergency blade. It is the hardest Audi key to replace when no working key is left.
The HU66 Blade and the Newer HU162T Blade
Audi keys use a high security blade with a track milled along the side rather than notches on the edge.
HU66
The HU66 profile is the blade on most Audi flip keys, and it is shared with Volkswagen, Skoda and Seat keys of the same years. It is cut by code or by reading the lock, as explained under car key cutting.
HU162T
Many newer Audi keys, including the MLB emergency blade on the A4 and Q5 from 2016, use the HU162T profile. It is thinner and needs the right cutter jaws.
Audi Key Replacement by Model
Four popular Audi models, and the key system each one uses.
Audi A3 Key Replacement
The A3 8P runs IMMO 4 and the A3 8V from 2013 runs MQB. Both are coded at the car, with or without a working key.
Audi A4 Key Replacement
The A4 B8 uses BCM2. Earlier cars are coded at the car in every case, while later B8 cars need online access for all keys lost. The A4 B9 from 2016 is MLB.
Audi Q3 Key Replacement
The Q3 uses a flip remote key, supplied, cut and coded at the car. The registration confirms the exact key before the visit.
Audi Q5 Key Replacement
The first Q5 uses BCM2, like the A4 of the same years. The Q5 from 2017 is MLB, where a spare needs a working key.
Audi Key Replacement Cost
Audi keys cost more than most makes because of the blade, the chip and the platform. These are typical UK figures.
| Job | Typical price |
|---|---|
| Audi key replacement | £135 to £250 plus VAT |
| New Audi key | £99 to £239 |
| Older Audi remote key | £150 to £250 |
| Smart or proximity key | £200 to £350 or more |
| Basic transponder key, older models | £180 to £280 |
| Flip key, A3, A4, A5 | £250 to £400 |
| Keyless key, Q5, Q7, A6, A8 | £350 to £550 or more |
| Audi dealer | £500 to £600 |
The price for your Audi is agreed in writing on the call, once the model, year and platform are known.
What Drives the Cost of an Audi Key
Four things move the price of an Audi key.
The Platform
IMMO 4 and MQB keys cost less to code than later BCM2 and MLB keys.
The Key Type
An Advanced Key for keyless entry costs more than a flip remote.
Whether a Key Still Works
A spare coded with a working key costs less than an all keys lost job.
The Time of the Call
A night or weekend visit can cost more, and that is said on the call.
Lost Audi Keys
On IMMO 4, MQB and earlier BCM2 cars, a new key is made from the car data and coded at the car, and the lost keys are removed so they can no longer start it. That removal is the step described under a car immobiliser reset. The full lost key process is covered under lost car keys.
When the Dealer Is the Right Route
On MLB cars with no working key, the dealer is usually the only route, and a dealer key can take 7 to 10 days to arrive. You are told this on the call, not at the car.

When an Audi Key Stops Working
Not every Audi key fault needs a new key. Three checks come first.
The Key Battery
A weak battery stops the remote and can stop an Advanced Key car finding the key. Most Audi keys use a coin cell such as a CR2032.
The Key Needs Coding Again
A key that locks the doors but will not start the car may just need coding again, which is car key programming rather than a new key.
The Keys Are Locked Inside
No new key is needed. The car is opened without damage, which is locked keys in car.

Questions About Audi Key Replacement in Worthing
The questions asked most about Audi keys, from the platform and cost to lost keys.
How much does an Audi key replacement cost in Worthing?
An Audi key runs from £135 to £250 plus VAT with a specialist, and higher for keyless keys on newer cars. A dealer runs £500 to £600. The price for your car is agreed on the call.
Which Audi key system does my car have?
It follows the model and year. An A3 from 2013 is usually MQB, an A4 or Q5 built before 2016 is usually BCM2, and an A4 from 2016 or Q5 from 2017 is MLB. The registration confirms it.
My Audi remote has stopped working but the car starts. What is wrong?
Usually the battery or the remote circuit, not the chip. A new battery comes first, then a remote car key repair if the buttons still fail.
The blade on my Audi flip key has snapped. Do I need a new key?
Not always. A new blade can often be cut and fitted to the same key, which is a car key fob repair rather than a new key.
How long does an Audi key replacement take?
Most Audi keys are cut and coded in about an hour at the car. An Audi dealer can take 7 to 10 days to supply a key.
What do I need to show for a new Audi key?
The V5C and photo ID in the same name. Company and lease cars need a letter from the keeper.
Can a locksmith make an Audi key if every key is lost?
On most older and MQB cars, yes. On MLB cars, all keys lost is very limited outside the dealer, and you are told that on the call before anyone sets off.
Does an Audi key have a chip?
Yes. Every Audi key has an immobiliser chip that has to be coded to the car, which is covered in more depth under transponder key programming.
Is a locksmith cheaper than the Audi dealer?
On most Audi models, yes. Specialist prices sit well below the £500 to £600 a dealer charges.
Do you cover Audi cars across Worthing and West Sussex?
