2010 Toyota Tacoma Key Fob Issue Sign In

2010
Toyota Tacoma
Engine V4 Manual Transmission 2.7 L
Miles 130,000

Hello,
I would like to present a scenario to explain my issue:
If I was on I-70 from Green River to Salina UT, there are no stops for at least 105 miles.

If I got out onto the side of the road for any reason, locked my truck with the key fob, and if that fob were to die from the battery or if I were to fall and break it. The 2010 I4 Manual Transmission Tacoma does not allow the engine to start, with the ignition key, without the fob unlocking the door.

I can't express how much I dislike this feature. Is there a way to disable all fobs and only allow the physical key to start the truck? (I also want to add there is no "push button" start, there is a physical key and my truck requires clutch start, the fob however has to be used to unlock the door for the truck to start. No matter how far away the fob is from the truck, I can not start the truck without the fob unlocking the doors first. Likewise, the physical key only unlocks the passenger door, the drivers door only unlocks with the fob or if you are already inside the vehicle).

I was wondering if there is an electrical component such as removing a fuse from the fuse box to resolve my issue.

However, my gut is telling me it's a programming component to disable the fob or re-write it; which is taking similar steps to program a fob which is found here:

Personally, I just want the FOB function disabled or removed, I'm thinking my last option is to take it to a Toyota shop and pay alot of money for them to disable the feature.
Any help is appreciated before I have to take it to a dealership.

Are you sure that's not an aftermarket security system? OEM systems don't work like that.

Are there any logos or names on the remote?

The Unlock Warning Switch and Drivers Door switch both signal the Immobilizer ECU. Which means the driver’s door has to be unlocked and opened to start the truck. This is identified because the physical key opens the passenger door but not the drivers door.

Next concern is when I am locked out and try to start the truck, nothing happens. There is no crank or turn over, the lights on the dash come on but it’s silent. Since the hazards are going off this seems to be triggering an Alarm System with Starter Disable.

The concern I have, is with what you stated. I don’t know if it was a factory install or a poorly installed aftermarket alarm system with starter disable. But my problem is the same, without the FOB, I can’t start my truck and as stated before I do not have a “push start” system, I have a physical key for the doors and ignition.

I've also gone in all Tacoma programming processes and nothing works such as disabling the alarm using the key in the ignition. I can't bypass this issue if it is an aftermarket security system.

That's not the way the factory system works.

The truck uses a transponder key that activates the fuel and ignition system. Nothing is connected to the door or the starter.

If yours works that way it has to be an aftermarket system and that means it can be removed and the wiring reconnected back. The factory system cannot be removed.
