Question 1

How do I spot a fake locksmith before I get ripped off?

Accepted Answer

A few things to watch for specifically when you're calling about a late-model Toyota. First, any real locksmith should be able to tell you upfront what programming equipment and process they use for a 2023 Tundra - this vehicle requires professional diagnostic tools, not a generic cloner. If they're vague about that, they may not be able to finish the job.

Second, the bait-and-switch pattern: a very low "service call" quote, then a surprise total once they're standing at your truck. Get a clear price range for your specific vehicle over the phone before anyone drives out.

Third, check for a real business presence. Reviews, a verifiable business name, and a tech who can speak to the actual process without hesitating. If something feels off on the phone, it usually is.

Question 2

What exactly is a smart key and why can't I just copy it at a hardware store?

Accepted Answer

Your 2023 Tundra uses a proximity smart key - the fob communicates with the vehicle's security system to authorize starting the engine. It's not just a shape cut into metal. The fob has to be electronically paired to your specific truck using diagnostic equipment before it will do anything beyond sit in your pocket. A hardware store key machine reads the physical cut of a blade. It has no way to touch the electronic pairing, which means a copied blade alone won't start your truck. Any replacement has to go through a programming step, period.

Question 3

What equipment do you use to program Toyota smart keys?

Accepted Answer

Professional-grade diagnostic tools - the kind that communicate directly with the vehicle's security system through the OBD port and handle the Toyota-specific enrollment sequences. For a 2023 Tundra, the programming process is not a simple plug-and-go; it involves authenticating with the vehicle's immobilizer and registering the new fob to the system. Not every locksmith has equipment current enough to handle the latest Tundra generation. I stay current on tooling specifically because late-model Toyotas will reject the job if the tool isn't up to date. If you're vetting someone, ask them directly what equipment they use for current-gen Tundra - a confident, specific answer is a good sign.

Question 4

I lost both keys to my 2023 Tundra. Is all-keys-lost harder than just adding a spare?

Accepted Answer

Yes, and it takes longer. When there are no working keys present, the programming sequence has a built-in wait period - the system runs a timed security countdown before it will accept new fobs. Add-a-key with one working fob skips that entirely and goes straight to enrollment. All-keys-lost also means the emergency blade needs to be decoded or the VIN used to generate the correct cut, since there's no working key to reference. The job absolutely gets done either way, but if you have one fob left even if it's weak and half-dead, keep it. Don't throw it away. It changes the timeline.

Question 5

My Tundra fob works sometimes and not others. Is it the battery or something worse?

Accepted Answer

Usually the battery. The CR2450 in this fob has enough capacity that it can show intermittent behavior before it fully quits - enough juice to ping the truck sometimes, not enough to do it reliably from more than a few feet away. Swap the cell first. Make sure it's the correct size and that it's seated flat with clean contact on both sides. If the behavior continues after a fresh battery that's properly seated, then it's worth looking at the fob itself - internal contacts can corrode, especially if the fob has been wet. And if it's been dropped hard, the board inside can shift just enough to cause problems that look like a dying battery but aren't.
