Question 1

I lost all my Subaru keys. Can you still make a new one?

Accepted Answer

Yes. All-keys-lost is one of the most complex calls we get on Subaru vehicles, especially on newer push-to-start models. We access the immobilizer system, reset the security module, and program brand new keys so the lost ones no longer start the car. On older Subaru transponder models, the AKL procedure includes a mandatory 15-minute immobilizer reset wait before new keys can be registered. On newer proximity models, the work may involve EEPROM or bench programming of the BIU module. Subaru dealers will tell you to tow the car in and some quote $2,000 or more. We come to you and handle the entire job on site.

Question 2

Do I need to tow my car to the dealer if I have no keys?

Accepted Answer

No. That is the dealer route, not the only route. Subaru dealers require the car to be towed in for all-keys-lost programming. On some newer models, dealers remove security modules like the BIU or smart-key ECU and ship them to Subaru for reprogramming, which means the car sits at the dealer for about two weeks. A BRZ owner facing all-keys-lost was quoted $1,800 at the dealer and then turned away because the car had a salvage title. A professional locksmith ultimately did the same job for $800. We bring Subaru specific tools to your location and handle the security access and programming right at your vehicle.

Question 3

How long does an all-keys-lost replacement take?

Accepted Answer

On older Subaru transponder models, the AKL procedure includes a mandatory 15-minute immobilizer reset wait, then key registration and remote programming immediately after, for a total on-car time of roughly 20 to 30 minutes once cutting is done. On newer proximity models like the BRZ or late-model Outback, EEPROM or bench work can stretch the process to 60 to 90 minutes including module access and reassembly. Compare that to the dealer route where module shipping alone can take two weeks. We handle Subaru AKL same-day in a single visit.

Question 4

What battery does the 2004 Subaru Baja key fob use?

Accepted Answer

The 2004 Subaru Baja uses a CR2032 battery. You can pick one up at most auto parts stores or pharmacies for a few dollars. When we make a replacement key, we always install a fresh battery so you are starting with a full charge. Pro tip: once you have your new key, pick up a spare battery and keep it in your wallet or glove box. A dead fob battery on a Subaru push-to-start can trigger a key not detected warning even though the key is fine.

Question 5

Can you make a spare at the same time so I have two keys?

Accepted Answer

Yes, and we strongly recommend it. Subaru AKL programming resets the immobilizer and only registers the keys presented during that session. That means adding a second key during the same visit costs far less than coming back later, since a separate visit would require running the full security procedure again. A 2020 Forester owner was told that losing both smart keys would require replacing the computer, sync box, and two other components for around $2,000. Getting two keys made now avoids that nightmare down the road.
