Planning a Spare Car Key in Jacksonville: Functions, Cost & Handover

Which functions do you want your spare key to perform?

A flat mechanical emergency key that only unlocks the driver's door, a transponder key that turns the ignition and satisfies the immobilizer, and a full push-button proximity fob with remote lock buttons are three different products. Clarify which functions you want included in your $150+ Jacksonville spare-key quote rather than assuming every 'spare' includes remote buttons.

If a spouse, teen driver, or employee in Jacksonville shares the vehicle, make sure everyone knows whether the backup key is a door-only blade or a full starting key, and test all agreed functions before the technician leaves.

Why must all existing working keys be present at the appointment?

When booking an additional-key visit in Mandarin, Southside, the Beaches, or Orange Park, tell us how many working keys currently start the car and keep every one of them with the vehicle. On many Ford, Honda, Toyota, and GM immobilizer systems, adding a key or clearing a slot requires cycling all retained keys during the same diagnostic session.

If your only remaining key is already cracked, bent, or failing intermittently, tell us when calling (904) 902-4771 so we inspect the blade and transponder health before duplicating a worn pattern.

Where should you store a spare key once it is programmed?

Keep your new spare key in a secure spot at home or with a trusted family member—never inside the glove box or center console of the same vehicle, where it cannot help during an $85+ lockout and creates a theft risk if a window is broken.

For proximity smart fobs stored at home, keep the spare at least 15–20 feet away from a driveway-parked car so the fob stays asleep and preserves its coin-cell battery.
