🔧 PRO TIP
The 2010 IS has a trim split worth knowing before you order anything. Not every IS from this year came with the Smart Key system. Some came with a standard transponder key that turns in the ignition cylinder. If your IS has a push-button start and door handle sensors, you have the Smart Key setup. If there's a key slot in the dash, you don't. The fob for the Smart Key version carries a CR1632 inside. That battery is thinner than what most people stock, so shops sometimes swap in the wrong cell. Wrong battery fits the tray, makes contact, and still reads weak. Check the battery type before you assume the fob is dead or needs programming. Also worth knowing: the fob contains an emergency insert blade tucked inside the case. If the battery dies completely, that blade is how you get in. Pull the release tab on the back of the fob, slide it out, and use it in the door cylinder.

2010 Lexus IS Smart Key Replacement - Fast, Affordable & Professional

I got a call from a woman in Cardiff-by-the-Sea, parked near the beach path. Her 2010 IS wouldn't acknowledge the fob at all. Door handles weren't responding, the push-button start was showing a key warning on the dash, and she'd already tried holding the fob up to the button, which is the move everyone tries when they've read half a forum post.

She had replaced the battery herself a few weeks earlier. That part was true. The CR1632 was in there. But when I opened the fob on the hood of the car, the battery was sitting slightly off-center and one of the contact clips had a small inward bend. Not dramatic. Just enough to make the connection unreliable, especially in the heat.

I straightened the clip, reseated the battery correctly, and closed the case back up. Then the part I never skip: full function check. I walked away from the car and tested door handle touch unlock on both sides, the lock button, the alarm button, and three consecutive push-button starts. Then I walked out to about thirty feet and ran it again.

Everything worked. She hadn't needed a new fob. She'd needed a fob that was actually making contact.

She mentioned she'd called the dealer first and was told to bring it in. No timeline, no promise it was even a battery issue. Coming to Cardiff-by-the-Sea and spending twenty minutes on a proper diagnosis cost her a fraction of what that appointment would have run, and she left with a working key the same afternoon.

“My Chevy key snapped while I was running errands in North Oxnard. He removed the broken piece from the ignition, cut a new blade, programmed the transponder, and tested everything thoroughly. The whole job was smooth and professional. Best automotive locksmith I have used.”

“My car keys were stolen on a cold evening and Nick drove all the way out to Santa Barbara. He got into my car, made a new key, and charged $100 less than another company. Friendly, skilled, trustworthy, and genuinely caring. Nick is a hero.”

“Tim is a hero. He programmed a master proximity key for a newer Volkswagen that multiple locksmiths refused to touch. He spent hours until late at night making sure every function worked perfectly. The skill level here is incredible.”

Lexus IS Mobile Service FAQ

Real costs, no dealer surprises

I lost all my keys to my 2010 Lexus IS. Can you still make a new one?
Yes, all-keys-lost on the 2010 IS Smart Key system is a job we handle on site. The process involves connecting to the OBD port with professional diagnostic equipment, accessing the vehicle's immobilizer, clearing the existing key registrations, and enrolling new ones. The emergency insert blade inside the fob also gets cut to your vehicle. Once it's done, any fobs that were lost are erased from the system and can no longer start the car. The dealer route for this job typically means a tow, a wait for parts if the fob isn't in stock, and a service appointment that could be days out. We come to you in Encinitas and handle the whole job in a single visit, usually under an hour from the time we arrive.
Do I really have to tow my 2010 IS to the dealer if I have no working keys?
How long does an all-keys-lost smart key replacement take on a 2010 IS?
My 2010 IS starts fine but stalls within a few seconds. I have a key, so what's going on?
