Key cutting and programming

Dealer vs Local Auto Locksmith: What’s the Difference?

Speed and convenience
A main dealer may require you to tow the vehicle to them and then wait days for a key to be ordered and coded. Our mobile service brings cutting and programming to you, often same day.
Cost-effectiveness
While every job is different, mobile locksmiths frequently offer better value than dealer routes—especially once you factor in towing, time off work, and waiting.
Capability
With modern diagnostics, OBD2 access, and EEPROM/immobiliser programming knowledge, we handle everything from older transponders to advanced smart systems.

Security, Insurance and Identification

Your security matters. We always:

Ask for proof of ownership and photo ID before producing keys
Keep your vehicle’s immobiliser data confidential and secure
Provide invoices and documentation suitable for insurance claims where required

If your keys were stolen, we can advise on next steps to secure your vehicle and support you with documentation. For practical steps, read our guidance on lost or stolen car keys.

Technical Expertise You Can Trust

Modern vehicles use complex anti-theft systems. We stay current with training and equipment to ensure safe, correct pairing:

Transponder and remote key coding
OBD2 key programming with authorised diagnostic tools
EEPROM key programming for certain models and situations
ECU and immobiliser programming and reset procedures where supported
Central locking synchronisation and remote pairing
Laser cutting and high-security key duplication

We also diagnose related issues, like steering lock faults, ignition barrel wear, and central locking problems. For more on ignition and lock issues, see car lock and ignition repair.

How long does it take to replace a car key?
