At Royal Key Supply, we specialize in professionally refurbished keys that pass rigorous quality standards, giving our customers an affordable and dependable alternative to new OEM keys.
This guide breaks down what refurbished keys really are, how they’re restored, who they’re best for, and how they compare to OEM and aftermarket options, so you can make informed purchasing decisions with confidence.
What Is a Refurbished Car Key?
A refurbished car key is a previously used OEM key that has been restored to function and appear comparable to a new unit. These keys undergo a multi-step refurbishment process that includes cleaning, cosmetic replacement, internal board flashing, and functional verification.
Unlike aftermarket keys, refurbished keys begin as genuine OEM components, meaning they maintain the original circuit board, transmitter strength, and programming reliability customers expect.

How Royal Key Supply Refurbishes Car Keys
Our refurbishment process is designed to match OEM quality standards while offering significant cost savings. Every key goes through the following steps:
1. PCB Cleaning & Inspection
The original OEM circuit board (PCB) is thoroughly cleaned and inspected for physical damage, corrosion, and signal integrity. In many cases, the PCB must also be flashed (resetting it back to a virgin state) so it can be correctly reprogrammed to the next vehicle.
2. Shell Replacement
When a key’s outer shell is heavily worn or damaged, we replace it with a new housing to bring back durability and a factory-fresh look. Since OEM manufacturers do not offer standalone shells without the internal boards, re-shelling requires the use of an aftermarket shell, which does not include the original logo.
3. Button Pad Replacement
Stretched, cracked, or non-responsive buttons are swapped for new pads to ensure clean, reliable function.
4. Battery Replacement (where applicable)
Keys with internal batteries receive new, tested power sources.
5. Emergency Key Refresh
If required, the emergency key blade is replaced.
6. Final Quality Control Testing
Each key is tested for:
- Signal output
- Button response
- Chip readability
- Overall durability
Anything that doesn’t meet our standards doesn’t go into inventory.
This process ensures consistent results, making refurbished keys a trusted choice for locksmiths and service professionals.
Refurbished vs OEM vs Aftermarket: What’s the Difference?
| Feature | OEM | Aftermarket | Refurbished |
|---|---|---|---|
| Cost | Highest | Low | Low-Medium |
| Chip Reliability | Excellent | Varies | Excellent (OEM board) |
| Housing Condition | New | New | Like-New (or replaced) |
| Programming Success Rate | Highest | Moderate | High |
| Best Use Case | Dealers, warranties | Budget repairs | Locksmiths, fleets |
Refurbished keys offer a strong middle ground between OEM and aftermarket options, especially when reliability and cost efficiency matter. For example, locksmiths often choose refurbished keys over aftermarket when dealing with vehicles known for programming sensitivity (such as Ford or Chrysler) because the OEM circuit board ensures a higher success rate and fewer callbacks. However, there are situations where a brand-new OEM key is required, such as brand new vehicles, vehicle security systems that require oEM software when key programming or when a customer specifically requests a factory-new key replacement.
The right choice ultimately depends on the customer’s needs, budget, and the vehicle’s compatibility requirements.
