Locking the OBD Install (Onboard Diagnostic Port)

I bought this little device because of this thread (taken right out of my driveway) and this video ( @Ilove2dubb 's car theft starts at 30 minutes). Or, maybe you don't want the dealer flashing over your favorite @PapaRee @TWTaco "tune" . If you park at the trailhead, or in the City, this device might be for you!

The OBD Locking Device was found over

$159 MITI OBD Protector | Metal OBD2 Port Lock Cap | Car Anti-Theft OBD Locking Device | Model R

here (yup, I paid full price ) with the parent company here (they're expensive because of the "niche market", custom fabrication, and coded security bolts, Patent Pending).

In theory:



Unboxing:



The Tacoma uses the OBD-R V1 with the plastic pacifier:



Push the pacifier into the OBD port. Use pliers to remove it:



Here's the cap ready for the security bolts:



Be sure the security bolts take properly. Don't do this:

Final Product (the security bolts and key are numbered with a lock code):



The Security key hides in a rubber cap with a keyring (hide it in your favorite teddy bear):





And don't forget to turn off the fob and keep it in a

I'm not to judge, just wanted to share. Que the kill switch argument in 3.. 2.. 1.. #stopboost

 

Here's another option if someone wants to save some money and have a standard key, but I haven't confirmed it works. Edit, search at your own risk. I didn't like the link.

 

Hopefully the price comes down by the time mine comes in. I emailed "geno's garage". They advertise something similar. No word from them yet.

Is the cover on this one metal?

 

They should just sell a dummy plug to plug in there. Then hide the real one up in the harness. I doubt they’d check for pins. And when they get a failure to communicate, maybe they’ll give up and think it’s the computer / cord / adapter etc.

 

A couple Toyota dealerships here in Ottawa (Canada) sell them. I was told all the service guys use them.

I like this idea!

 

Hey what’d u call me?!


@daveeasa can u build us one that automatically notifies the police when something is plugged into it?

 

This looks good, but unfortunately, you can't have the lock on the genuine port.

 

There is always room for improvement. Appears the Dummy OBD in only plugged into the factory OBD for a power source. So, alter the Dummy OBD to use a constant power fuse or a battery pack. Then relocate the factory OBD and put a OBD lock on it, if so desired.

 

So ... when a cartoon *copies* your key fob they also need access to the OBD port?

Or is accessing the OBD port another way to steal the truck?

 

Great idea!

 

Think of it this way, if someone lost all their fobs and had their truck towed to the dealer, the dealer should be able to program a new key fob using Toyota's Techstream software and some "tokens". A thief should be able to duplicate that if they have a mini laptop with Techstream and an extra fob. An OBD lock should prevent them from easily doing that.

 

What I don’t get, is techstream only allows you to program a key if you have at least ONE key that’s currently programmed to the truck. Unless there’s some higher level techstream that allows u to bypass that. So I don’t get how people can steal a truck without a currently programmed key.

and IF they’re using a boosted key to be able to program a new key, then why not just use the boosted key to begin with? Because techstream uses the RFID to verify the “current programmed” key. Hope all that makes sense lol.

 

Maybe I was incorrect about the Techstream.

All-Keys-Lost situation; a key programming and diagnostic "tablet" that reads the key data from the immobilizer computer through the OBD port, and then transfers it to a key simulator/emulator, then transfers it to a "smart key to be learned" key fob.

 

Below is from the DummyOBD website. It's generic/broad statement covering many makes/models, it does make sense, especially with the All Keys Lost scenario described above:

So How are they doing it?
Firstly, thieves get into the car by breaking the window in a way that doesn’t set off the ultrasonic alarm sensor. Then they attach a sophisticated reader to the on-board diagnostics connector and once connected they can disable your vehicle immobiliser, de-activate the alarm, code new keys and then drive away! All of this can be done in less than two minutes. Most OBD ports are located on the driver side of the vehicle under trim above your shin!

By law, the data accessible by the OBD connector has to be openly available, meaning the vehicle manufacturer can’t encrypt the information.

 

I'm still curious if the key fob is copied remotely do they still need to access the OBD port or can they just drive away?

 

Interesting. I didn’t know that existed. That’s from that other thread?

 

That last paragraph interesting sounds like the "right to repair law" b.s. We have in Massachusetts. Sounds like a easy fix to all this might be for the manufacturer to allow the owner of the car to password protect access to the cars computer/obd port. If a dealer or shop needs access u grant them access by unlocking it.
