When you have a new key programmed for a Jaguar, whether at a dealer or with a mobile specialist, the warranty terms matter. Here is what to expect and what to ask for.
Dealer Key Warranty
A Jaguar dealer programming a spare key or all-keys-lost will typically apply JLR’s standard parts warranty to the key blank — usually 12 months on parts. The programming labour may be covered under a separate workshop warranty of 90 days to 12 months depending on the dealer. Ask for the warranty terms in writing at handover.
Independent Specialist Warranty
AJ Auto provides a 12-month warranty on all key parts and programming. This means if the key blank fails or the programming develops a fault within 12 months, we return and resolve it at no additional charge. The warranty applies to the key itself — it does not cover physical damage, loss, or fob battery replacement, which are consumable items.
What the Warranty Covers
Parts: the key blank, electronics, and emergency blade. Programming: the KVM profile written during the session. If the key stops authenticating, passive entry stops working, or any programmed function fails within the warranty period without physical damage being the cause, we attend and resolve it.
What to Ask For
Regardless of whether you use a dealer or independent specialist, request a written warranty document with the parts covered, the duration, and the contact for claiming. A verbal warranty is worth very little.
| Service | AJ Auto Price | Main Dealer Estimate |
|---|---|---|
| Jaguar spare key | From £180 | £400 to £900+ |
| Jaguar all keys lost | From £250 | £700 to £1,500+ |

What We See in Practice
Warranty discussions around Jaguar keys come up regularly and the pattern we see is consistent: owners told by a previous provider that a key is under warranty discover the warranty covers the hardware but not the programming, or vice versa. Our approach is to give a written 12-month warranty covering both the hardware and the programming work. In practice, key failures within 12 months are rare when correctly programmed and the vehicle’s battery health is good. The most common warranty-adjacent situation we encounter is an owner whose vehicle has developed a battery fault causing intermittent key detection, which is a vehicle issue rather than a key defect.
Frequently Asked Questions
What warranty does AJ Auto offer on replacement Jaguar keys?
All keys supplied and programmed carry a 12-month warranty covering defects in the key hardware and programming. If a key fails to operate within the warranty period without physical damage, it will be assessed and replaced.
What does a Jaguar dealer warranty on keys cover?
Dealer key warranties typically cover the key hardware but not always programming-related issues, and the warranty period varies. Always confirm the exact terms at the time of purchase because key warranty conditions are not standardised across the dealer network.
Is an aftermarket Jaguar key as reliable as an OEM one?
Quality aftermarket remotes from reputable suppliers are built to the same functional specification as OEM keys and perform identically in use. Budget-grade aftermarket keys with poor build quality do exist and these are not used or supplied.
What voids a Jaguar key warranty?
Physical damage, water submersion beyond incidental moisture, opening the case and disturbing the circuit board, or using the key with a battery of incorrect specification are the most common causes. Normal wear, including minor case scratching, does not void the warranty.

When to go to a dealer instead
If your vehicle is still under JLR factory warranty and the fault is covered, take it to a dealer. Warranty repairs are free and no specialist can match that. If you need a recall fix, the dealer is the right call. Outside of those two situations, a mobile JLR specialist will be faster, cheaper, and will attend at your location.
