Spare & Transponder Car Key Replacement

Why You Need a Spare

Why Spare Keys Are Essential

A spare car key is one of the simplest ways to avoid a stressful and costly emergency. Losing your only key — especially a modern smart key or transponder key — can mean a long wait and a high bill. Having a spare means you're always prepared. CT Locksmith Service LLC makes getting a spare key fast and affordable throughout New Haven County, CT.

• Avoid being stranded if you lose your primary key
• Share a key with a family member or trusted person
• Much cheaper to make a spare now than to replace a lost key later
• Spare keys can also serve as a backup in case of key damage or wear

Key Types

Regular Spare Keys vs. Transponder Keys

Not all spare keys are equal. Modern vehicles require transponder key programming in addition to physical key cutting — a standard hardware store copy won't start your car.

• Standard spare keys — basic metal cut copies for door locks (older vehicles)
• Transponder keys — chip-embedded keys that must be programmed to your vehicle's immobilizer; a cut-only copy will not start a modern car
• Smart key spares — full proximity key programmed to your vehicle
• Key fob copies — remote entry programmed for your specific vehicle
• We cut and program all types on-site at your location or our Bethany store
