Question 1

What is the cheapest way to replace a smart key for a 2023 Jaguar I-Pace?

Accepted Answer

Call a mobile locksmith before you call the dealer or order anything online. The dealer route on a late-model Jaguar typically involves a tow if you have no working key, a multi-day wait, and labor rates that add up fast. Owners who go straight to the dealership on all-keys-lost jobs regularly report quotes well above a thousand dollars once the module work and programming time are included.

Buying a fob online and bringing it somewhere to program sounds cheaper, but there is a real catch on I-Pace and other recent JLR vehicles: some fobs from this era are tied to a single programming event. A used fob that was already paired to another car will not program to yours. You need a verified, unpaired fob and the right diagnostic equipment to match it to your specific vehicle's immobilizer. When you call us, we bring both.

Question 2

How much more does all-keys-lost cost compared to just adding a spare?

Accepted Answer

A lot more, and the gap is wider on modern Jaguars than on most other brands.

When you still have one working key, adding a spare is a standard programming job. The immobilizer already has an active key to reference, the module is in a known state, and the process is comparatively quick.

When every key is gone, the immobilizer has to be accessed at a deeper level. All stored key identities get wiped, and new ones are enrolled from scratch. On recent I-Pace and other JLR models, that process requires professional diagnostic access and takes longer. Some owners on JLR forums have reported dealer quotes ranging from around fifteen hundred dollars to well over two thousand for all-keys-lost work, depending on whether the dealer also recommends module replacement.

The single best thing an I-Pace owner can do is get a spare made while one working key still exists. It costs significantly less and takes far less time. If you are already in the all-keys-lost situation, it is still solvable, it just costs more than it would have with a spare in hand.

Question 3

Do aftermarket Jaguar I-Pace fobs actually work, or is it a waste of money?

Accepted Answer

It depends entirely on the source and the condition of the fob.

A new, unprogrammed aftermarket fob from a reputable supplier can work fine once it is properly programmed to your vehicle. Some owners have sourced these at a fraction of the dealer part price and had them programmed successfully.

The problem is used fobs sold online. On recent JLR platforms, a fob that was already coded to another vehicle may not be reprogrammable. You can buy it, pay someone to try to program it, and end up with nothing usable. That scenario happens often enough that it comes up regularly in I-Pace owner forums.

We carry verified, unpaired fobs for this vehicle. If you already bought one online and want to find out whether it is viable before paying for programming, that is a reasonable first question to ask when you call.

Question 4

My I-Pace fob battery is fine but the car sometimes doesn't detect the key. What's going on?

Accepted Answer

This is one of the more common complaints I see from I-Pace owners. The car shows a key-not-detected warning or acts sluggish to unlock on approach, even with a fob that tested fine.

A few things to check first. Certain smartphones, especially when in a back pocket next to the fob, can interfere with the key signal. It is a known enough issue that JLR has acknowledged signal interference from devices carried close to the fob. Try keeping the phone and fob separated and see if the behavior changes.

The other thing worth checking is the fob's internal battery contacts. Even a new battery can cause intermittent failures if the contact plate has a slight bend or corrosion. Open the fob, reseat the battery, and verify the contacts are clean and making solid connection.

If neither fixes it, the issue may be on the vehicle side, specifically the antenna or the module reading the key signal. That requires diagnostic work to trace properly.

Question 5

Can someone drive away with my I-Pace using a relay attack on the smart key signal?

Accepted Answer

Yes, and this is a real concern that comes up a lot in I-Pace owner communities. Relay attacks work by amplifying the fob's signal from inside your home so the car thinks the key is nearby. No key cloning, no bypass, just signal extension. The car unlocks and starts.

The straightforward countermeasure is a signal-blocking pouch, sometimes called a Faraday pouch, for your fob at home. They are inexpensive and widely available. Keep the fob in one when it is not in use and the signal cannot be extended. Some owners also use a steering wheel lock as a secondary visual deterrent.

The I-Pace's value and profile make it a target worth protecting this way. It takes about five seconds to drop your fob in a pouch when you get home.
