3 Different Types of Car Keys Available
Not all car keys are created equal. The kind of key you have determines how easy or expensive it can be to replace.
Here are the main types you’ll come across:
1. Traditional Keys
These contain a physical metal key shaft that you need to insert into the ignition cylinder to start the car. They’re usually found on older vehicles. Since these don’t contain electronic components, they’re easy to duplicate.
There are two subtypes under this:
- Laser-cut keys: These keys have a thicker shank with intricate grooves carved into the face of the blade rather than the edges. They require specialized machines to duplicate, which makes them less common at everyday locksmiths or hardware stores.
- Switchblade keys: These combine a traditional or laser-cut blade with a folding design. The key shank flips out from the fob at the press of a button. While the blade works like a standard key, the folding mechanism makes it more compact and stylish.
2. Transponder Keys
Transponder keys look similar to traditional keys but have an electronic chip embedded inside. This chip communicates with the car’s immobilizer system (a security feature in modern vehicles to prevent unauthorized starting). This ensures the car can only start when you use the correct key.
3. Smart Keys (Keyless Entry Fobs)
Found on modern vehicles, smart keys eliminate the need to insert anything into the ignition. They use radio signals to allow for keyless entry and push-button start. As long as the fob is nearby, the car will unlock and start with ease.
What’s the Average Cost of Key Fob Replacement?
Generally, expect to pay between $25 and $500 for a replacement key fob. Let’s check out the cost of different types.
A. Range
The estimated costs for key fob replacement are:
- Traditional keys: $25 to $100 (No programming involved; a locksmith or dealership can quickly cut the key for you.)
- Laser-cut keys: $150 to $300 (No programming needed)
- Switchblade keys: $200+ (Full replacement usually includes programming)
- Transponder keys: $100 to $250 (Key chip must be programmed)
- Smart or keyless entry fobs: $200 to $500+ (Requires specialized programming)
B. Factors Affecting Cost
Besides the key type, here are the factors that determine your final bill:
- Vehicle make and model: Luxury or newer vehicles often require specialized keys, making them more expensive to replace.
- Materials used: Higher-quality metals or durable plastics can increase production costs, which is reflected in the replacement price.
- Part vs. complete key replacement: Replacing only the key blade or fob casing is usually cheaper than replacing the entire key assembly.
- Geographic location: The final price can vary by location. Costs in major cities like Los Angeles and New York are higher than in smaller towns.
- Programming fees: Keys with chips or electronic components must be programmed to the vehicle. Some locksmiths may charge an additional $120 to $150+ for this.
- Dealership vs. locksmith: Dealerships can offer OEM keys with guaranteed compatibility, but usually charge more. In contrast, locksmiths may provide cheaper aftermarket options, but their services are limited to specific car models.
- Additional costs: You may also end up paying extra charges for locksmith services or towing your car to the dealership if your vehicle isn’t drivable due to a lost key.
PRO TIP: Replacement key fobs often don’t come with the hidden emergency key inside the fob. If you’re replacing a fob due to a faulty transmitter, keep the original emergency key handy to insert into the new fob and avoid extra rekeying costs.
How Long Does It Take to Get a Car Key Replacement?
The time needed to replace a car key depends on the type and whether programming is required. With an experienced locksmith, it can be as quick as 10 to 30 minutes, but some keys take up more than an hour.
Here are the estimates:
- Traditional metal key: 10 to 30 minutes, just to cut
- Laser-cut key: 30 to 60 minutes due to precision cutting
- Switchblade key: 30 to 60 minutes, including programming
- Transponder key: 30 to 60 minutes with programming
- Key Fobs: 5 to 45 minutes, depending on complexity
- Smart Keys: 45 to 90 minutes with extra programming steps to integrate with the car’s electronic system
5 Ways to Save Money on Key Fob Replacement
Here are a few smart steps that can help lower the expense:
- Check your warranty: Some vehicles include free or discounted fob replacements within the warranty period.
- Check your insurance: Certain car insurance policies cover key fob replacement. So review your plan to see if you’re covered.
- Explore aftermarket options: These can be a budget-friendly alternative to OEMs, especially for older models. But you’ll need to check compatibility and see if the shop offers a warranty.
- Compare prices: Get quotes from multiple dealerships and locksmiths before deciding.
- Buy a backup early: It’s a good practice to have a spare fob on hand. This can save you from the expense and stress if your keys are lost.
Can You Get a Replacement Key Made for a Car Using the VIN?
Yes, a locksmith or dealership can cut a replacement key using your car’s Vehicle Identification Number (VIN), but you’ll need to provide proof of ownership (such as your registration and ID).
That said, the process may be complex for newer vehicles. Some cars require the vehicle to be physically present so the new key can be programmed correctly. You can’t just order a working key online.
Can You Reuse a Key Fob?
Yes, but it depends on the vehicle and the fob’s compatibility.
Some fobs can be reprogrammed for a new car, while others are permanently locked to the original vehicle. Secondly, the fob’s condition matters. If the chip or circuit board is damaged, reuse isn’t possible. However, you can swap the shell or battery.
That said, if reprogramming is possible, it’s definitely a cost-effective option compared to getting a new one.
