Question 1

Are you licensed and insured to work on Audi vehicles?

Accepted Answer

Yes. EZ Car Keyz is a California BSIS licensed locksmith company, fully insured, and carries Vehicle Security Professional certification through NASTF. That certification means we've been vetted to access manufacturer security data for Audi and other makes, which matters on a vehicle like the A5 where the immobilizer and body control module are tightly integrated and programming without the right credentials and tooling can leave you worse off than when you started.

We operate under a real business name with verifiable reviews. You can look us up before you call, and the price I give you on the phone is the price on the invoice.

Question 2

How do I know you're not a scam locksmith?

Accepted Answer

Scam locksmiths are a genuine problem, and Audi owners get targeted specifically because the work is expensive even from legitimate shops. The pattern is always the same: a low quote on the phone, then a string of add-on charges once the tech is at the car and you're stranded.

EZ Car Keyz has well over 100,000 followers across YouTube and TikTok where you can watch us do this exact work on Audi and other European vehicles. Marked van, firm phone quote, price doesn't move at the car. That's how it goes every time.

Question 3

Will the replacement key work exactly like my original?

Accepted Answer

Yes. We program the fob to the vehicle so that lock, unlock, and the other buttons all function the way they should. Proximity behavior at the door handle gets tested on site before we pack up.

One thing worth knowing: if you've had any control module replaced on the car, there's a component protection layer in the Audi system that can block a new key from pairing even when the programming procedure runs clean. We check for that before we sell you anything. Sometimes the issue is the vehicle, not the key, and it's worth diagnosing correctly the first time.

Question 4

My 2013 A5 shows a key warning on the dash but the fob battery is fine. What's actually going on?

Accepted Answer

This comes up more than you'd think on these cars. A few different things can cause a key-not-detected warning even when the battery is fresh.

First, the fob's internal contacts can oxidize or shift slightly, especially if the battery was ever replaced by prying instead of popping the case properly. The battery reads fine on a tester but the connection inside the fob is intermittent.

Second, the antenna that receives the fob signal is built into different parts of the car depending on where you're standing. The door handle antennas and the interior antennas are separate. If detection fails only at the door but works fine once you're inside, that points to a door-side antenna or wiring rather than the fob itself.

Third, on cars where the body control module has been touched, component protection can make the system act like it simply doesn't see the key at all. Diagnosing which of these is actually happening is step one. Don't replace the fob until you know which problem you have.

Question 5

I bought a replacement fob online for my 2013 A5. Can I just program it myself?

Accepted Answer

No DIY path exists for this. The 2013 A5 smart key system requires professional diagnostic equipment to register a new fob to the vehicle. There is no button sequence or ignition-cycle trick that works here. The aftermarket fob you bought online is just a blank until it gets paired, and pairing requires the right tooling and the right access. Bring what you have and we'll handle it.
