Genesis Key Fob & Smart Key Replacement Services
Published Date: Nov 6, 2025
You dropped your fob, and now your Genesis won’t respond. Suddenly, you’re locked out and the replacement path can seem complicated. Many drivers assume the dealership is the only option. However, there’s another way: a professional automotive locksmith who comes to you. This guide from Sure Lock & Key explains the Genesis key fob replacement process, the quickest options for your model, and how to get back on the road fast.
Genesis Smart Key Replacement: What You Need to Know
Whether you drive a Genesis G70, G80, or G90, your smart key is more than just a remote. It’s a sophisticated piece of technology. Inside are rolling security codes and a transponder chip that talks to your Genesis immobilizer. That’s why a random online remote won’t start the car without proper pairing.
When you need a Genesis smart key replacement, you generally have two choices:
- Dealership: A dealership will provide a genuine Original Equipment Manufacturer (OEM) fob. Expect the highest price and the possibility of a tow if you don’t have a working key.
- Automotive Locksmith: A qualified automotive locksmith can source the correct OEM or high-quality aftermarket unit and program it on site. Sure Lock & Key performs Genesis G90 key fob programming (and G70/G80/GV models) using professional diagnostic tools, so you skip the tow and the long wait.

Driving an older Hyundai Genesis key fob (2009-2016, before Genesis became a standalone brand)? The process is similar — those keys also carry immobilizer chips that must be paired by a pro.
Steps for a Genesis Key Fob Replacement
Getting a new key for your Genesis involves three main steps. While it may be tempting to buy a key online and find instructions on how to reprogram a key fob yourself, modern Genesis vehicles require specialized diagnostic equipment. DIY methods are generally ineffective and can even damage your car’s computer.
Here is the professional process:
- Identify your exact key fob. Find the part number/FCC ID on the back of the fob (you may need to remove the mechanical key). This matches your frequency and buttons — for example, a Genesis G70 key fob may differ from a Genesis G80 smart key. Sure Lock & Key can also look this up by VIN (vehicle identification number) and confirm compatibility before you buy.
- Purchase and cut the new key. You can purchase the fob through your locksmith or the dealer. A locksmith often supplies the same unit for less and includes a new “blank” emergency key. If you still have one working key, they trace it. With a lost Genesis key, they cut a key by code from your VIN and verify ownership on site.
- Program the fob to your vehicle. This is the make-or-break step. A technician connects to the OBD-II port (the car’s diagnostic port), removes any missing keys from memory, and pairs the new remote and transponder. Remote functions and push-button start are tested before we leave. For the full process, visit our car key fob programming service page.
Get Back on the Road with a Trusted Locksmith
A tow and a day at the dealer aren’t your only choices. For fast, secure Genesis key fob replacement, a mobile Sure Lock & Key Locksmith team meets you where the car sits — home, office, or curbside. We source the correct unit, cut the emergency blade, and complete Genesis smart key replacement and programming in one visit.
Want to avoid a repeat emergency? While we’re there, it’s smart to get a duplicate car key and store the FCC ID/part number in your phone. That small step saves time and stress if you ever face another lost Genesis key situation.
Frequently Asked Questions
Can I program a new Genesis smart key myself?
Generally, no. Modern Genesis smart keys (G70, G80, G90, and others) require specialized diagnostic equipment to pair the new fob with the vehicle’s immobilizer system. DIY programming guides rarely work on these cars, so professional service is the reliable route for Genesis key fob replacement.
What should I do if I lose my only Genesis key?
If you’ve got a lost Genesis key, call a mobile automotive locksmith first. Keep your VIN ready and be prepared to show a photo ID and your vehicle registration. A mobile professional can come to you, cut a new key, and program a new fob on site, saving you a tow.
Will my old, lost key fob still work after I get a replacement?
It shouldn’t. During programming, a professional should deregister all missing keys from the car’s computer. That way, if someone finds your old fob, they can’t use it to unlock or start your vehicle.
Can a locksmith make a key for an older Hyundai Genesis?
Yes. A qualified automotive locksmith has the equipment and fobs needed to replace and program keys for older Hyundai Genesis models (2009-2016) as well as the new Genesis brand vehicles.
