Losing a car key or having one break off in the ignition ranks high on the list of things nobody plans for. Whether you’re at the Eau Gallie Square parking lot, stuck outside Publix on Wickham Road, or stranded after a long day at the Melbourne office, needing a car key replacement comes with questions — and usually some sticker shock if you go the wrong route.
Here’s what actually matters when you need a replacement car key in Brevard County, and how to avoid overpaying or waiting longer than necessary.
Not All Car Keys Are the Same
The cost and complexity of replacing your car key depends entirely on what type of key your vehicle uses. There are four main types, and they’re very different in terms of what’s involved.
Traditional metal keys are the simplest. These are plain cut keys with no electronics — common on vehicles made before the mid-1990s. A locksmith can cut one on the spot in minutes.
Transponder keys look like regular keys but contain a small microchip in the plastic head. The chip communicates with your car’s immobilizer system. Without the correct chip signal, the engine won’t start even if the key turns the ignition. Most vehicles from 1996 onward use some version of this technology.
Key fobs with remote start combine the transponder chip with buttons for locking, unlocking, and sometimes remote start. These require both cutting and programming.
Smart keys and proximity fobs are the keyless entry systems where you never take the key out of your pocket. Push-button start vehicles use these. They’re the most expensive to replace and require specialized programming equipment.
Dealership vs. Locksmith: The Real Difference
The dealership will always be an option for key replacement, but it’s rarely the fastest or cheapest one.
Dealerships typically need to order the key blank, which can take 3–7 business days. You’ll also need to tow your vehicle to them if you don’t have a spare. The total cost — including the key, programming, and any tow fees — often runs $300 to $800 depending on the vehicle.
A mobile automotive locksmith comes to you. There’s no towing involved, and most replacements are completed in under an hour at your location. For the same work, you’ll typically pay 30–50% less than the dealership price.
What Affects the Cost
Several factors determine what you’ll pay for a car key replacement:
Vehicle make and model is the biggest factor. A basic transponder key for a Honda Civic costs far less than a smart key for a BMW X5. European and luxury vehicles generally have more complex key systems.
Whether you have a working key matters significantly. If you have at least one working key, the locksmith can often clone it or use it to program the new one more quickly. If all keys are lost, the process involves accessing the vehicle’s onboard computer to program from scratch — which takes longer and costs more.
Key type directly impacts price. A simple transponder key might cost $75–$150 all-in, while a full smart key with proximity can run $200–$400 through a locksmith.
Time of service can also factor in. Emergency calls at 2 AM will typically cost more than a scheduled daytime appointment.
Common Mistakes to Avoid
Don’t try to program a key yourself with YouTube videos. Modern vehicle security systems have anti-tampering measures. Failed programming attempts can lock out the vehicle’s computer entirely, turning a $150 job into a $500+ one.
Don’t buy blank keys from Amazon or eBay expecting a locksmith to cut and program them for cheap. Many aftermarket blanks use inferior chips that fail within weeks. A reputable locksmith uses OEM-spec blanks that are guaranteed to work.
Don’t wait until you lose your only key. Getting a spare made while you still have a working key is dramatically cheaper and faster than an emergency replacement with all keys lost.
When to Get a Spare Made
If you’re down to one key, treat it like a warning light on your dashboard. Getting a spare now — while it’s convenient and affordable — is the smartest move. Most locksmiths can make a spare transponder key for $75–$150, and it takes about 30 minutes.
Compare that to the $300+ you’ll pay for an emergency replacement when that last key inevitably disappears.
