2024 Genesis G70 Key Replacement

2024 G70 key specs

Facelifted G70s use one of two fob families. Earlier refreshed cars typically carry a six-button fob (FCC ID TQ8-FOB-4F36) with remote start and headlight buttons and a CR2032 cell. Later builds moved to a five-button fob (TQ8-FOB-4F75M44) with a Hitag AES chip and a CR2450 cell. The two are not interchangeable, and cars with and without remote start use different parts, so we match your exact part number before programming anything.

What's specific to the 2024 G70

The 2024 Genesis G70 is the third of 5 model years in the G70 IK facelift (2022–2026), so it shares its key system with the rest of that run, which makes replacement parts easy to source.

At 2 years old, a 2024 Genesis G70 is usually still on its original keys and fob batteries. The most common call for a car this new is a second key, since many buyers leave the dealer with only one, or a replacement after a lost fob.

Key options for the 2024 Genesis G70

• Smart proximity key (push-to-start). A smart or proximity key lets a 2024 Genesis G70 open when you touch the door handle and start with a push of a button while the fob stays in your pocket or bag. Antennas in the doors and cabin send out a low-frequency wake-up signal; the fob answers on a higher radio frequency with an encrypted reply, and the car only allows a start once it confirms the fob is inside. When the fob battery is weak, that conversation fails, which is why most designs include a backup: hold the fob against the start button or set it in a designated pocket. The owner's manual shows where, and it's worth checking before you need it.

How the Genesis immobilizer works on the G70

• The 2022 refresh dropped the manual transmission, and every facelifted G70 still starts by push button.
• Two fob families appear in this run: an earlier six-button fob and a later five-button Hitag AES fob.
• Supplier listings show the five-button Hitag AES fob (95440-G9720) as fitting 2023-2025 G70s, so some 2023 cars may carry either fob.
• Later five-button fobs take a CR2450 cell rather than the CR2032 used in earlier G70 keys.

Programming a 2024 G70 key

Both fob families register through the OBD-II port with the VIN-based PIN, but the later Hitag AES fobs need current tool software and the correct blank, so we confirm coverage by VIN before the visit. Programming can relearn the full key list, so gather every fob first. All-keys-lost is usually possible on the earlier fob type; on late builds we check first and tell you if the dealer is the better route.

Later builds with Hitag AES fobs need current tool coverage; we confirm by VIN and refer you to the dealer when needed.

Lost every key to your G70?

Losing every key to a Genesis is a bigger job than adding a spare, but it doesn't automatically mean a tow to the dealer. Because Genesis programming depends on the VIN-based PIN rather than on an existing working key, the all-keys-lost procedure on many models looks a lot like adding a key: we open the car, connect through the OBD-II port, enter the PIN and register new fobs, then cut the emergency blade from the key code. Coverage is less certain on the newest builds. Fobs with Hitag AES chips and recently refreshed models are where aftermarket tool support is most likely to lag, and phone keys always run through the Genesis account. We check coverage by VIN before driving out, verify your ID and registration on arrival, and tell you on the phone if your car needs the dealer instead.

1. Gather your documents and the VIN. Call with the year, make, model and VIN if you can read it through the windshield, plus where the car is parked. Those details let us confirm whether your Genesis G70 can be done on-site and bring the right key, so the first trip is the only trip.
2. Get into the vehicle without damage. If the car is locked, we open it with non-destructive tools such as an inflatable wedge and a long-reach rod, or by picking the door lock. Some vehicles need a careful approach to avoid triggering the alarm, which can interfere with programming later.
3. Originate a new key from the car. Originating a key means building it without a sample. The door lock usually reveals most of the cuts; any it doesn't are worked out by test-cutting and trying the ignition or a second lock. The finished blade should feel like a factory key, not a forced fit.
4. Program the key to the immobilizer. Next, the new key is introduced to the car's security system. Many vehicles allow this through the OBD-II port with a PIN or security procedure. Some all-keys-lost cases require reading a module on the bench, and a few platforms only allow dealer programming, which we'll tell you up front.
5. Erase missing keys and add a spare. Once the car starts, we remove the lost keys from memory wherever the system allows, so they can't start the engine if someone finds them. Making a second key during the same visit costs much less than a repeat all-keys-lost call down the road.

Why a spare key pays for itself

• Electronics fail without warning. A fob dropped on concrete, run through the washing machine or soaked at the pool can quit for good. With a second programmed key, that's an annoyance you fix on your own schedule, not a stranded car that needs attention today.
• A spare stored safely at home rescues you from a locked car with the fob sitting on the seat, a key dropped somewhere along a hiking trail, or a fob that stops responding on a busy morning. Keep it indoors, never in a magnetic box under the bumper.
• When you sell or trade in the vehicle, buyers and dealers expect two keys. A missing key can come up during an appraisal or a private-sale negotiation, so having both on hand keeps the conversation about the car, not about what it will cost the next owner to replace one.

Dealer or mobile locksmith?

The biggest difference between a dealership and a mobile locksmith is where the work happens. A dealer programs keys in its service bay, so if every key is lost, the car usually has to be towed there, and you work around the service department's schedule and the time it takes to order a key by VIN. Julian's Locksmith brings the cutting machine, key blanks and programming equipment to the car, whether it sits in your driveway, a workplace lot or a parking structure. For a 2024 Genesis G70 we can program on-site, that means no tow and no shuttle rides back and forth. The trade-off is real, though: on vehicles where only the dealer can program keys, a tow or appointment may still be necessary, and we'll say so before you spend anything on our visit.

G70 key battery

Most fobs for a 2024 Genesis G70 open along a small slot in the seam; a coin or a plastic pry tool works better than a screwdriver, which chews up the housing. If the fob hides a mechanical blade, slide it out first, since the case often opens from that gap. Note which side of the old cell faces up, swap in a fresh replacement, and press the halves together until they click all the way around. Handle the new battery by its edges, because skin oil on the faces can hurt contact. In most cases the fob keeps its programming through a battery change, so test lock, unlock and start, and you're done.

How the job works

1. Identify the exact key your G70 uses. Every job starts with the VIN, the trim and a look at any key you still have. From those we confirm the keyway, the transponder or smart-key chip, the remote frequency, the FCC ID and the button layout. Two Genesis G70 keys that look identical can carry different electronics, so this step keeps the wrong part from ever reaching the car.
2. Verify ownership before any work. Before cutting or programming, we compare your government photo ID with the vehicle registration or title and check that the VIN on the paperwork matches the VIN on the dash. If the registration is locked inside, we open the car first, confirm the documents, and only then make the key.
3. Get the key code or decode the lock. If you still have a working key, we can read its cuts directly and check them against the factory depths for the Genesis keyway. A worn key gets corrected back to spec during this step, so the new key turns crisply instead of reproducing years of wear in a fresh piece of metal.
4. Cut the blade on-site. Cutting happens right beside your car. For a smart key, that means the emergency blade hidden inside the fob; for a transponder or remote-head key, it's the main blade you'll use every day. We deburr the cuts and check the fit in each lock so nothing binds or sticks later on.
5. Program the chip, remote or smart key. Programming tells the car's computers that the new key belongs to the vehicle. Transponder chips are added to the immobilizer, remote buttons to the body control module, and proximity fobs to the keyless system. If a step requires dealer-only access on your G70, you'll have heard that before we arrived, not halfway through the job.
6. Test everything and clear out old keys. Before we leave, every function gets checked: doors, trunk or liftgate, panic button, remote range, engine start, and the emergency blade in the driver's door. If keys are missing, we delete them from the car's memory where the system allows, so a lost key can no longer start the engine.

What affects the price of a G70 key

• The type of key. Price follows complexity. The more the key does, the more it costs to replace: brass blade, then chip, then remote buttons, then full keyless entry and push-button start. If your G70 came with different key styles by trim, the one your car actually uses is the one that sets the quote.
• Programming complexity and security access. Two cars with similar-looking keys can program very differently. Newer platforms often guard key programming behind encrypted access or paid credentials, while older systems allow straightforward OBD-II pairing. We check the exact procedure for your VIN before quoting, so the number reflects the real work involved.
• Blade style and cutting. Traditional edge-cut blades are quick to cut. High-security laser-cut blades, with a groove milled into the side, need a specialized machine and more care, and the blanks themselves cost more. If we have to decode a lock to find the cuts, that adds labor as well.
• Travel, timing and extra repairs. Because we come to you, the distance from our San Bernardino base and the time of the call play a part. So does anything we find along the way, such as a worn ignition cylinder or a seized door lock. You hear about each item and get a quote before we start work.

Common Genesis key problems

• Buttons that work only sometimes after a drop or a trip through the washing machine usually point to board damage inside the fob. A fresh coin cell won't fix that; a new programmed fob will.
• Ordering a fob by model year alone often goes wrong. Genesis used several fobs per model with different buttons, chips and batteries, so the part number and FCC ID printed on your current fob are what count.
• On the GV60 and the Electrified models, a drained 12-volt battery can make the car ignore a perfectly good fob. We test that small battery before anyone spends money on a new key.
• Plenty of drivers have never seen their emergency blade. It slides out of the fob, and on several models the driver's door keyhole hides under a cap or cover on the handle that has to come off first.

Tips from a mobile locksmith

• Southern California heat is hard on keys. Fob batteries drain faster, plastic housings turn brittle, and rubber button pads crack when a key spends summer afternoons on a dashboard or in a sunny cup holder. Carry the fob with you or keep it shaded, and replace batteries before summer rather than after they fail.
• Be careful with discount fobs from online marketplaces. A listing may match your remote's shape while using a different frequency, chip or FCC ID, and many used smart keys are locked to their original vehicle. If you already bought one, send us the listing or a photo before the visit so nobody pays for a programming attempt that can't work.
• When a key's head cracks or its blade bends, replace it before it fails. A transponder chip can slip out of a split head, and a bent blade can break off inside the ignition or door lock, turning a simple key replacement into an extraction and repair job. Small symptoms are the inexpensive time to act.

Proof of ownership

Making car keys is regulated work in California. Locksmiths are licensed and overseen by the Bureau of Security and Investigative Services under the Locksmith Act, Business and Professions Code section 6980 and following, and Julian's Locksmith holds company license LCO7891. Verification protects you more than anyone: a locksmith who will make a key for whoever asks will also make one for someone who wants your car. We record your name, the vehicle and its VIN on a work order, and we politely decline jobs where ownership can't be established. You can look up our license at search.dca.ca.gov.
