JLR Key For OEM 315MHz
JLR Key For OEM 315MHz replaces the original smart key on compatible Jaguar Land Rover models. This page serves both information seekers and buyers, giving technicians, workshops, and owners a clear technical overview of the key, its frequency, and ordering steps.
Product Overview
The JLR key system secures the vehicle, provides remote access, and improves driver convenience. In the applicable models, the key transmits on a 315 MHz radio frequency, which the vehicle must recognize to operate correctly.
We design this replacement key to match the OEM‑specified 315 MHz profile, so it works as a drop‑in substitute when the original key is lost, damaged, or worn out. Because modern JLR keys rely on encrypted communication, selecting the correct frequency eliminates radio‑mismatch problems.
Technical Application
Technicians replace a key by first confirming the vehicle’s original key type, market region, and immobilizer version. They then fit the OEM 315 MHz key, cut the mechanical blade (if required), and program the unit using JLR‑approved diagnostic tools.
The 315 MHz frequency ensures the remote button communicates reliably with the car’s body‑control module. After fitting, technicians synchronize the key’s security code with the vehicle, which restores full locking, alarm, and start‑stop functions.

Why Frequency Accuracy Matters
Using a key with the wrong frequency prevents the remote button from reaching the vehicle, which disables lock‑/unlock and alarm functions. The correct 315 MHz signal lets the car’s receiver decode the command instantly, reducing troubleshooting time.
We recommend confirming the frequency before purchase, because a mismatched key forces a costly re‑programming cycle or a replacement purchase.
Fitment and Installation Notes
First, verify the VIN‑derived key specification in the vehicle’s service data. Then, compare the part number “OEM 315 MHz” with the original key label.
After you receive the key, cut the blade to match the door lock (if the key includes a mechanical cut). Use a JLR‑approved scanner to enroll the key’s transponder ID, then test all remote functions before returning the vehicle to the customer.
