“Modern car keys aren’t just bits of metal they’re encrypted devices that talk to your vehicle’s brain.”
If you own a Land Rover, Range Rover or Jaguar, you already know your key is far more advanced than an ordinary one. Behind that sleek fob sits a microchip, an immobiliser system, and a layer of security designed to protect your vehicle from theft.
At AJ Auto JLR Key Specialist, we don’t cut keys. Our focus is on key coding and programming for all JLR models up to 2026, using the same diagnostic tools trusted by main dealers only faster, more convenient, and far more cost-effective.
Understanding the difference between cutting, coding, and programming helps you know what your vehicle truly needs when a key stops working or goes missing.
Key Cutting – The Mechanical Part
Key cutting is the traditional process of shaping a metal blade to match your car’s locks or ignition barrel. It’s still common for older cars, but less relevant for modern JLR models that rely on smart keys and push-to-start systems.
Earlier Land Rovers and Jaguars used physical blades like HU101 or HU92, which could unlock the doors and turn the ignition but that’s where their role ended. They didn’t talk to the car’s electronics or immobiliser.
Purpose: To make a mechanical key that physically fits and turns the lock.
Relevance for JLR Owners: Very limited most models from 2010 onwards use keyless fobs instead.
AJ Auto Note: We don’t cut keys. Instead, we specialise in the electronic pairing and system integration your car truly depends on.Key Coding – The Digital Handshake
Coding is where the technology begins. Inside every smart key is a transponder chip that holds an encrypted ID. When you press start, your vehicle checks for a matching code before it allows the engine to run.
At AJ Auto, we code that chip precisely to your vehicle’s immobiliser and control units (KVM, RFA or BCM). This ensures the new key is fully recognised and authorised just like your original.
Purpose: To link your key’s unique chip ID to the vehicle’s immobiliser system.
Tools Used: Lonsdor K518 Pro, VVDI Key Tool Plus, ACDP, and dealer-level diagnostic interfaces.
When Needed: When all keys are lost, when you want a new smart key, or when replacing a faulty fob.We complete all coding without replacing modules or altering the vehicle’s data preserving your car’s original configuration.
Key Programming – The Smart System Setup
Programming is the next layer. Once the chip is coded, the key must be programmed to control all the smart and remote functions locking, unlocking, boot release, and keyless start.
Our team uses OEM-level software to integrate your key with the Body Control Module (BCM) and Remote Function Actuator (RFA), ensuring every feature works exactly as it should.
Purpose: To activate the remote and proximity functions of the key.
Tools Used: Dealer-grade diagnostic tools and encrypted programming systems.
When Needed: When adding or replacing any JLR smart key or keyless fob for 2010–2026 models.Each programmed key is tested on-site to confirm smooth keyless entry, start, and full remote operation before delivery.

Frequently Asked Questions
1. Do you need to cut a key for modern Land Rover or Jaguar models?
No. Most recent Land Rover, Range Rover and Jaguar vehicles use smart proximity keys rather than traditional blades. These rely on electronic coding and programming. AJ Auto does not cut keys we specialise in key coding and programming up to 2026.2. Is key coding the same as key programming?
Not quite. Coding connects the chip in your key to the immobiliser so the car can start. Programming sets up remote and keyless functions like locking and start/stop. Both are essential for a complete smart key.3. How long does key coding and programming take?
Usually 30 to 90 minutes, depending on the vehicle. We complete all work at your location no dealership visits required.4. Can you program a new key if I’ve lost all my keys?
Yes. We can code and program a brand-new smart key even if every key is lost. We extract the necessary data from your car’s modules to generate a fully working key with no module replacement.5. Do I need to visit a dealership for key programming?
No. AJ Auto provides a mobile key programming service across England and Wales using dealer-level software, saving you time and money.6. What models do you cover?
We work on all Land Rover, Range Rover and Jaguar models from 2010 to 2026, including Defender, Discovery, Range Rover Sport, Velar, Evoque, Jaguar XF, XE, F-Pace, E-Pace and I-Pace.7. What’s the difference between a locksmith and a key programmer?
A locksmith focuses on mechanical key cutting and lock repair. A key programmer, like AJ Auto, handles the electronic side coding, synchronising and activating smart keys.8. Can AJ Auto clone or duplicate my existing smart key?
Yes. If you already have a working key, we can safely clone or program a spare with the same encryption, giving you a reliable backup.
