Question 1

Do you use OEM or aftermarket keys on Chevrolet vehicles?

Accepted Answer

We use professional-grade keys from tested suppliers that match the factory specifications for your specific vehicle. The fob needs to match the correct button count, frequency, and internal configuration for your year and model, or programming will either fail outright or produce a key that works intermittently.

The cheap fobs floating around on Amazon are the gamble. Locksmiths who let customers supply their own sourced fobs report a high failure rate - not always because the fob is counterfeit, but because enough small variables are off. On a 2020 Corvette with a seven-button fob, a mismatch in the internal hardware means the security handshake won't complete correctly. We carry what actually works, not what looks right in a product photo.

Question 2

How long will a replacement key last on a 2020 Corvette?

Accepted Answer

Years, with normal use. The electronics inside are durable. The CR2450 battery is the only consumable, and swapping it every year or two is all the maintenance this fob needs.

The most common physical failure owners report is the plastic shell cracking around the key ring loop or the buttons wearing soft over time. If the shell goes, the internal board can often be transferred to a new housing without any reprogramming, as long as it's handled carefully and nothing gets damaged in the move. That's a cheap fix. What you want to avoid is dropping the fob hard on pavement repeatedly - the internal board is not indestructible, and a cracked board means a full replacement and reprogramming.

Question 3

What if the new key stops working after a few weeks?

Accepted Answer

Call me. I'll come back out.

Every key I program gets tested before I leave - lock, unlock, push-button start recognition, every button function. If something fails under normal use after I've left, that's on me to fix or replace. I've heard from owners who paid serious money to a locksmith and ended up with buttons that only fired every tenth press, with no callback support. That's not how I run things. My work is warranted and I stand behind it.

Question 4

Can I program a second fob myself, or do I need a scan tool every time?

Accepted Answer

You need a scan tool every time on this vehicle. There is no onboard add-a-key sequence, no ignition-turn trick, no button combination that registers a new fob to the 2020 Corvette. The immobilizer requires a proper security handshake through the diagnostic port using professional programming equipment. This comes up constantly on Corvette forums when owners buy a spare fob online thinking they'll save some money on the programming side. The fob itself you can source wherever you want, but pairing it to the car requires the right tools and someone who knows the procedure. Bring it to me or factor in a programming visit before you buy anything.

Question 5

The fob range on my 2020 Corvette dropped suddenly. Do I need a new key?

Accepted Answer

Not necessarily. Sudden range drop is almost always the battery before anything else. The CR2450 in this fob can read as "present" to the car from a foot away even when it's nearly dead, so the fob feels like it's working until it doesn't. Swap the cell first.

If fresh CR2450 doesn't bring the range back, the next thing to check is whether something changed in your environment - a new wireless device in the garage, a second fob sitting right next to the first one, or even the fob bouncing around loose in a bag with metal objects. Interference and physical damage both kill range.

If you've ruled all that out and range is still weak, the antenna inside the fob may be damaged, or the car's receiver may have a separate issue. At that point it's worth having someone take a look rather than guessing at parts.
