Question 1

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

Accepted Answer

Three things to check before anyone touches your car. First, look up the business name and confirm it has a real address and consistent reviews on Google and Yelp. Scam operations cycle through different business names that all route to the same call center, and the reviews are thin or obviously fake. Second, ask for a firm phone quote specific to your vehicle. A real locksmith will ask for the year, model, and whether you have any existing keys before giving a number. If the answer is a suspiciously flat rate for any car any time, walk away. Third, ask for a California BSIS license number on the spot. Every locksmith company operating in this state is required to have one and should be able to give it to you immediately. If they hesitate or change the subject, that tells you everything.

Question 2

What exactly is a remote head key and how does it work on the 2013 Legacy?

Accepted Answer

A remote head key combines the ignition key blade and the fob into a single unit. The transponder chip is embedded in the key head and communicates with the vehicle's immobilizer when you turn the ignition. If the immobilizer does not recognize the chip, the engine will not run, or it will crank and immediately shut off. The four buttons on the fob handle the remote functions separately over radio frequency. Both sides of that unit, the chip and the remote, have to be working correctly. A key that is cut right but not programmed will not start the car. A key that is programmed but worn down from years of use can cause intermittent no-start issues because the blade is not making clean contact in the cylinder. It is one piece of hardware doing two different jobs.

Question 3

What equipment do you use to program a 2013 Subaru Legacy key?

Accepted Answer

For the 2013 Legacy, OBD-based programming tools handle transponder registration through the diagnostic port. I also carry EEPROM reading and writing equipment for bench-level work on situations where the standard OBD route is blocked, such as all-keys-lost scenarios where the vehicle has no working key to reference. Lishi picks and decoders take care of non-destructive entry and key origination from the lock when needed. Subaru's immobilizer architecture on this generation is well-supported by professional tools, but the key word is professional. If a locksmith cannot tell you specifically what they use on a 2013 Legacy transponder system, that is worth asking about before you hand over the car.

Question 4

I lost all my keys. Can a new remote head key still be made for my 2013 Legacy?

Accepted Answer

Yes, and it is a job I do regularly. All-keys-lost on this generation requires going through the immobilizer via the OBD port to clear the old key data and register the new one. There is no working key to clone from, so the process is a full origination: cut the blade to the vehicle using the key code or by decoding the lock, then register the transponder so the immobilizer accepts it. It takes longer than a straight duplicate, typically 45 minutes to an hour on site, but it is completely doable without a dealer visit. Once the new key is registered, the old lost keys are erased and cannot start the car.

Question 5

The fob range on my 2013 Legacy has gotten terrible. I'm practically pressing it against the door now. What is going on?

Accepted Answer

Usually the CR2032. These fobs are sensitive to battery voltage drop, and reduced range is often the first sign before buttons start failing entirely. Swap the battery first. If the range stays bad after a fresh CR2032 is seated correctly, the next suspect is the internal antenna trace on the fob board, which can crack if the housing has taken a hit. A cracked board still powers on and may still start the car via the transponder chip, but the radio signal for the remote functions is weak or gone. At that point a replacement fob housing with a board transfer, or a freshly programmed replacement unit, is the fix. The good news is that neither scenario means anything is wrong with the car itself.
