🔧 PRO TIP
The 2010 Legacy (fifth generation, B4 platform) uses a Texas Instruments TK5561A (Texas 4D, ID62) transponder chip inside that CWTWBU766 remote head key. Not a high-theft target, so most of my calls are lost-key or last-key-standing situations, not stolen car recovery. If you're down to one working key and the remote buttons are getting sluggish, swap the CR2032 first. But don't wait on getting a spare cut and programmed, because all-keys-lost on these costs more and takes longer than an add-a-key.

2010 Subaru Legacy Remote Head Key Replacement - Fast, Affordable & Professional

A chiropractor near Marina Park in Ventura called me on a Wednesday around noon. He had patients booked every thirty minutes until five. His 2010 Legacy was sitting in the office lot, dead to the remote head key. Push the lock button, nothing. Try to start it, the immobilizer light on the dash just blinked and the engine wouldn't turn over. He'd already swapped in a fresh CR2032. No change.

He couldn't leave work. Couldn't schedule a tow during business hours. Couldn't push it to the weekend because he drives that car to a second office Thursday mornings.

I got there between his 12:30 and 1:00 patients. Used my DAT17 Lishi to decode and verify the mechanical cut, then plugged into the OBD-II port under the dash. The Subaru immobilizer on these uses a challenge-response handshake with the ID62 transponder, so I cleared the old key data and reprogrammed his CWTWBU766 fob fresh. All four buttons came back: lock, unlock, trunk, panic. Engine started clean, no immobilizer light.

He walked out between patients, saw the key sitting on a napkin on his desk where I'd left it, and just kind of nodded like the whole problem had never happened. That was the best part. No drama, no tow, no waiting room. Car never left the spot.

“The dealership quoted me $600 for a new Honda key. EZ Car Keyz did it for $225, same day, cut and programmed at my house. Works perfectly. Everyone should know this is an option.”

“A+ service at an even better price. Tim was a lifesaver. I lost my original and only key for my Audi and he was willing to come to my location at 8pm the same day. He worked fast, communicated clearly, and made sure everything worked before leaving.”

Subaru Legacy Mobile Service FAQ

Real costs, no dealer surprises

How long does the Subaru dealer take for a 2010 Legacy key replacement?
Depends on the situation. If they have the CWTWBU766 fob in stock and you still have a working key, an add-a-key at the dealer can be done in about 30 minutes once you're actually in the bay. But that's the best case. More often, the fob has to be ordered by VIN, which pushes you into a second appointment days later. For all-keys-lost on push-to-start Subarus, some dealers pull the Body Integrated Unit (BIU, part number 88281-AJ40A on this generation) and ship it to Subaru for a security reset. Owners on SubaruOutback.org have reported that round trip alone taking two weeks. With me, add-a-key is typically under an hour on site.
