Emergency 2004 Lexus GS key fob made from scratch by EZ Car Keyz Simi Valley CA
🔧 PRO TIP
The 2004 Lexus GS uses a remote head key, meaning the fob and the key blade are one unit, not separate pieces. The transponder chip lives inside that head, so if the blade gets copied at a hardware store without programming the chip, the car will crank but won't start. The battery in these is a CR1616, which is thinner than the CR1632 a lot of people grab by mistake. Wrong battery looks like it fits, makes contact, and then gives you weak signal or nothing at all. If the range has been shrinking or the lock response is getting sluggish, start with the correct CR1616 before assuming the fob is dying.

2004 Lexus GS Remote Head Key Replacement - Fast, Affordable & Professional

I got a call from someone up in the Big Sky neighborhood in Simi Valley. He had a 2004 Lexus GS and had been using a key that looked fine on the outside but had been giving him grief for weeks. Intermittent starts, fob buttons working one day and not the next. He finally had a morning where it just refused to cooperate and he was already running late.

He thought it was the battery. He had swapped a battery in, but grabbed the wrong one at the drugstore. Common mistake. The one he put in was slightly thicker and was bowing the contact plate just enough to make intermittent connection instead of a solid one.

I pulled up in my van, popped the fob open on my workbench, and the problem was visible immediately. Wrong cell, contact slightly deformed from the pressure. I seated the correct CR1616, straightened the contact, and tested every button from across the parking area before I even handed it back. Lock, unlock, the third button, all crisp.

While I was there I checked that the blade was cut correctly and hadn't worn to the point of causing ignition issues. It was fine. The whole job took maybe twenty minutes.

He mentioned he'd been quoted a full fob replacement by the dealer. For a wrong-battery installation. Getting a second opinion on a key problem costs nothing when you call a mobile locksmith first.

“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 GS Mobile Service FAQ

Real costs, no dealer surprises

What is the cheapest way to replace my 2004 Lexus GS key?
Call a mobile locksmith before you call the dealer. Lexus dealers tend to quote remote head key replacements as a bundled service that includes the part, cutting, and programming, and the total lands well above what a mobile locksmith charges for the same result. With EZ Car Keyz, we come to you in Simi Valley, cut the blade to your vehicle, and program the transponder and the remote functions on site. No appointment weeks out, no tow bill, no separate line items for each part of the job. Call us first and you will hear a number that is a fraction of what the dealer wanted.
How much more does an all-keys-lost job cost compared to just adding a spare?
Are aftermarket remote head keys for the 2004 Lexus GS worth buying?
My 2004 GS starts fine but the fob buttons stopped working. Is the whole key bad?
Can I program a second key for my 2004 Lexus GS myself at home?
