What Affects the Cost of a Car Key Replacement?

Before we dive into price ranges, it’s important to understand the key factors that influence how much you’ll pay:

• Key Type: Standard manual keys or remote keys keys are cheaper than electronic keys like smart fobs/proximity keys.
  
• Vehicle Make & Model: Luxury or imported cars usually require more expensive keys and specialised programming.
  
• Technology Level: If your car uses proximity sensors, push-to-start ignition, or keyless entry, you’ll likely need a more advanced (and pricier) key.
