Welcome to JLR KEY LONDON
Mobile Jaguar & Land Rover Key Replacement in Hertford
Hertford’s old-town streets and the Lea Valley villages around it (Ware, Hertford Heath, Hoddesdon) are regular ground for us. We cover the SG13/SG14 area daily — our most common Hertford job is a spare-key request for a family Range Rover or Defender at a riverside property, sometimes followed by a battery diagnostic on a fob that’s been damp from a riverside walk.
We service every JLR model. Defender L663 smart keys are programmed via OBD diagnostic; older Discovery 4 (L319) keys still in stock for legacy fleet vehicles.

Hertford FAQs
Q. My Land Rover Defender L663 won’t recognise the key after a wet walk along the Lea — what now?
A. Likely water damage in the fob. We’ll diagnose, swap the internal board if recoverable, or programme a fresh fob — usually 60–90 minutes.
Q. Do you cover Ware and Hoddesdon as well?
A. Yes — both are standard same-day callouts from our Hertford beat.
