Question 1

What is the cheapest way to replace my 2020 Jaguar I-Pace key?

Accepted Answer

Call a mobile locksmith before you call the dealer. Jaguar dealers on a smart key replacement for the I-Pace are not cheap, and that is before any towing, waiting time, or module-related surprises that can come up when they get into the system. A mobile service comes to you, does the work on-site, and the total is a fraction of what the dealer route tends to run.

One thing to avoid: buying a used fob off a resale site and expecting to save money. Some keyless modules on late-model Jaguars will not accept a fob that was already enrolled to another vehicle. You end up with an unprogrammable fob and still need a new one anyway. We source verified, enrollable keys for the I-Pace specifically, so you are not paying twice.

Question 2

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

Accepted Answer

A lot more, and on the I-Pace that gap is real.

When you have a working key, adding a spare is a standard enrollment job. The module already has a valid key in memory and just learns an additional one alongside it. When all keys are lost, the module has to wipe everything and start from scratch. That process is more involved, takes longer, and on some late-model Jaguar vehicles can raise questions about whether the module itself needs to be addressed.

Jaguar I-Pace owners on forums have reported dealer quotes for all-keys-lost situations ranging well into four figures, sometimes with module replacement bundled in whether it was needed or not. The straightforward advice is the same every time: get a spare made while you still have a working key. It costs less, takes less time, and keeps you out of the all-keys-lost situation entirely.

Question 3

Do aftermarket Jaguar I-Pace keys actually work, or should I stick with OEM?

Accepted Answer

Aftermarket fobs for the I-Pace exist, and some work fine once properly enrolled. The issue is not always the key itself. It is whether the key has ever been programmed before. A fob that was already enrolled to another vehicle may not be accepted by your car's keyless module, and there is often no way to know that from a listing photo.

We carry verified new aftermarket fobs for the I-Pace that are enrollable and tested. That said, the programming labor is the same regardless of whether the fob is OEM or aftermarket. If you want to source your own fob, contact us first so we can confirm compatibility before you buy.

Question 4

My I-Pace shows a key warning on the dash but the fob battery is new. What else could it be?

Accepted Answer

A few things. First, verify the replacement CR2032 is seated flat with both contacts making solid connection. A slightly tilted battery can read as a weak signal even when brand new.

If the battery is seated correctly and you are still getting a key-not-detected warning, the more likely culprits are the door handle antennas or the interior cabin antenna that the car uses to locate the fob. I-Pace owners have reported cases where one door handle stops triggering unlock reliably while the other side works, which points to the antenna on that specific handle rather than the fob itself. If the warning only appears in certain situations, like approaching from one side or with the fob in a specific pocket, that directional pattern matters and helps narrow it down quickly.

Question 5

Can someone relay-attack or steal a 2020 I-Pace with keyless entry?

Accepted Answer

It is harder than on older keyless vehicles. The I-Pace uses a proximity verification system that measures the physical distance between the fob and the car rather than just detecting whether a signal is present. Classic relay theft works by amplifying a fob's signal from inside your house to fool the car outside. That technique is significantly less effective on vehicles that check signal timing and proximity the way the I-Pace does.

That said, no system is completely theft-proof. The practical advice most I-Pace owners follow is keeping the fob in a signal-blocking pouch when it is not in use, especially overnight. It is a simple habit and removes the relay-attack vector entirely regardless of what the car's system is doing on its end.
