Audi Car Key Exeter — Replacement, Programming & Lockout

Mobile Audi key specialist covering Exeter and Devon — HU66, HU162T, MQB and MLB platform. VAG immobiliser, smart key and all-keys-lost. Fixed price, 24 hours.

Audi shares the VAG group's MQB and MLB platforms with Volkswagen, SEAT and Škoda — but Audi's premium positioning means dealer key replacement costs are consistently among the highest in the market. From an A3 MQB transponder fault to an A6 MLB smart key issue, a Q5 proximity key not detected or an R8 all-keys-lost — we carry Audi-specific VAG diagnostic equipment to resolve it at your vehicle, at a fraction of the Audi dealer cost.

Audi Key Systems — What You Need to Know

Audi uses VAG group immobiliser systems shared with Volkswagen, SEAT and Škoda, across two distinct platforms — the transverse MQB (A3, Q3, TT, A1) and the longitudinal MLB (A4, A6, A7, A8, Q5, Q7, R8). The platform determines the programming protocol.

Audi VAG immobiliser — MQB vs MLB platforms

Audi shares the VAG group IMMO system with VW, SEAT and Škoda across two architectural platforms. MQB (Modular Transverse) covers A3, Q3, TT and A1. MLB (Modular Longitudinal) covers A4, A5, A6, A7, A8, Q5, Q7 and R8. Each uses a different OBD communication protocol — the correct equipment for one platform will not programme the other.

Pricing
Audi key replacement — how we quote

Audi dealer key replacement is among the most expensive of any mainstream brand. We use identical equipment at independent rates. MQB and MLB Evo keys are more complex than pre-2013 IMMO3/4 keys, which is reflected in the quote.

  • › HU66 key (IMMO3/4, pre-2013 models)
  • › HU162T MQB key (A3 8V/8Y, Q3, TT 8S)
  • › HU162T MLB key (A4 B9, A6 C8, Q5 FY)
  • › All-keys-lost (any Audi model)

Common Audi Key Problems We Fix in Exeter

The most frequent Audi key faults we attend across Exeter, Devon and Somerset.

🔑
Audi A3 8V / 8Y MQB Key Sync Fault
The MQB 4th/5th-gen transponder is the most common Audi programming job in Exeter. After flat battery, ECU work or key deletion, the BCM loses the key credential. We restore via MQB seed/token OBD at your vehicle. A3 8V and 8Y are our most frequent Audi callouts.
💾
Audi A4 B9 / Q5 FY MLB Key Programming
A4 B9 and Q5 FY use MLB Evo platform with different OBD protocol to MQB. MLB key programming requires Audi MLB-specific diagnostic tools. All-keys-lost on A4 B9 or Q5 FY is a high-value job we handle with priority.
📶
Audi A6 C8 / A7 / A8 Smart Key Fault
A6 C8, A7 and A8 KESSY smart key proximity failure is often a depleted key battery rather than a programming fault. We diagnose the root cause before recommending replacement.
📡
Audi TT 8S / Q3 F3 MQB Programming
TT 8S and Q3 F3 are MQB-based and subject to the same key sync faults as A3 8V/8Y. We restore via MQB OBD seed/token exchange. Attended across Exeter and Devon regularly.
🚌
Audi Q7 4M / A6 C7 All-Keys-Lost
Q7 4M all-keys-lost requires MLB Evo OBD. A6 C7 uses IMMO4 HU66 OBD. Both covered with appropriate tools. High-value jobs treated with urgency wherever located in Devon.
🔧
Audi R8 Key Fault
R8 key programming — 42 (HU66) or 4S (HU162T) — handled with appropriate priority. R8 all-keys-lost is attended promptly. Call to confirm platform and we quote and attend.

How We Programme Audi Keys On-Site

Audi key programming is platform-specific. Here is what happens when you call us for an Audi key in Exeter or Devon.

1
Identify the Audi platform and IMMO generation
Model, year and chassis code (8V, B9, C8 etc.) identifies whether MQB, MLB/MLB Evo or older IMMO3/4 pre-platform. EV models use separate protocols. Fixed price confirmed on the call.
2
Cut the blade at your vehicle
HU66 (pre-2013 IMMO3/4) or HU162T (MQB/MLB post-2013) cut at your location. Smart key / KESSY models require no blade cutting.
3
VAG platform OBD programming
IMMO3/4: standard VAG OBD. MQB (A3 8V/8Y, Q3, TT 8S): MQB seed/token. MLB/MLB Evo (A4 B9, A6 C8, Q5 FY): Audi MLB-specific OBD. EV: MEB/PPE protocol.
4
Test and verify
Key tested in door, remote and ignition or push-button start. VAG immobiliser light confirmed off. Payment on completion only.

ⓘ For all-keys-lost Audi jobs, an all-keys-delete sequence is carried out before the new key is programmed as the sole authorised credential. Ownership verification required.

Frequently Asked Questions — Audi Car Keys Exeter

Audi key pricing varies by platform (IMMO3/4, MQB or MLB Evo) and key type. Pre-2013 IMMO3/4 models are the most cost-efficient. MQB and MLB Evo require seed/token OBD which is more involved. Fixed all-in price before travelling — always significantly less than Audi dealer rates. No call-out fee. Call 01392 925673 with your Audi model and year. See our pricing page.

MQB covers transversely-engined Audi: A3 (8V, 8Y), Q3 (F3), TT (8S), A1 (GB). MLB covers longitudinally-engined models: A4 B9, A5, A6 C8, A7, A8, Q5 FY, Q7 4M, R8. Each uses a distinct OBD protocol. Equipment for MQB will not programme an MLB model and vice versa. We carry dedicated tools for both platforms.

Typically a MQB BCM key credential sync loss, not a key failure. We restore via MQB OBD seed/token exchange at your vehicle. In most cases no new key is needed. Call before ordering a replacement.

Yes — all-keys-lost is available for all Audi models across IMMO3/4 (pre-2013), MQB (transverse post-2013) and MLB/MLB Evo (longitudinal post-2013). EV models (Q4 e-tron, e-tron GT) use MEB/PPE protocol — we confirm coverage on the call.

Yes — Q7 (4L IMMO4 HU66 and 4M MLB Evo) and A8 (KESSY smart key MLB) are within our coverage. High-value vehicles attended with priority anywhere in Exeter and Devon.

Yes — Audi e-tron (MEB-based) and e-tron GT (PPE platform) are covered. EV platform programming uses a different protocol to standard VAG OBD. Confirm your Audi EV model and year on the call so we bring the correct equipment.

Yes — the credential programmed to your Audi's BCM is identical whether programmed by us or an Audi dealer. Both use VAG OBD protocols (MQB, MLB or IMMO3/4 as applicable). Physical HU66 or HU162T blanks from the same professional supply chain. The difference is cost and on-site convenience.

IMMO3/4 key (HU66, pre-2013): 30–50 minutes. MQB key (A3 8V/8Y, Q3, TT 8S): 45–70 minutes. MLB key (A4 B9, Q5, A6 C8): 50–75 minutes. Smart key / KESSY: 60–80 minutes. All-keys-lost: 75–120 minutes. Accurate estimates confirmed on the call.
