06 Tundra with annoying alarm, Karr or ?

EDITED
My wife just bought a 02/06 Tundra 2WD with 328xxx miles, do not knock before reading LOL.

As I was looking at it ( 700.00 US dollars with title and 2 keys ) I thought she went froot loopy on me LMAO!

Turns out it was a hand me down through the family we know, OK, no big deal starts right up runs fine, took it for a quick spin that is when I noticed the truck still had some, no a lot of spunk left.

As I parked it to start work on it the alarm started acting a fool ( I hate AM Alarms ) when I disconneted the battery. SO I chaulked it up to low battery/disconnect reset issues, then I found a little red blinking button on the left side of the dash ( yea I bet you heard this 1 before )

I took the fuse cover off and started through it and 'horn bomb' started.



My wife tells me it is to reset the alarm ... ? Why, I ask, she said that is the reason I bought it as YOU could figure it out, I asked her millage does not count here does it LOL, she says my F250 has 438xxx miles and still going ..... SO I shut up.

Though I can rebuild engines and auto transmissions, this truck has me stumped as to the maker of this annoying headache of a auto security system. Any kind of help with removal or what ever it takes to stop this 'horn bomb' ?

First off, before digging too deep, you may want to read the first two replies of this thread, and you'll understand why we don't talk smack on mileage, 330k miles is 'just broken in': https://www.tundras.com/threads/so-you-wanna-buy-just-bought-a-1st-gen-tundra-eh.115928/

Unless you like dying, make sure the lower balljoints have been replaced with ONLY OEM units within the last 100k miles.
Unless you like bricking your engine, if V8, make sure the timing belt has been replaced with OEM parts (Aisin brand) within the last 100k miles, along with tensioner, water pump.
Unless you like putting money into something that's gonna die, though the sand I'm seeing on the floorboard tells me you may be in the west/southwest USA, take a fine tooth comb to the frame to check for rust-through/cracks in the most common spots.

That said, the LED I'm seeing there doesn't look like a dealer-installed KARR or SECURIKEY+ alarm. That looks like any generic run-of-the-mill alarm any audio/security shop in town may install, from Voxx/Clifford/Viper/Avital/etc.

Now. Here's where we need you to do something for us. Get up under the dash. Trace those wires back to the black box it's attached to. Get some pics of labels, brand name, model number, anything. Can give better advice when you do so.

But seriously. Read the first two replies of that thread you linked, AFTER you get us more info on the brain box of the alarm, which is always mounted up under the driver side of the dash.

 

I would start by locating the head unit and unplug the harness and keep it unplugged. This should do the trick for Karr alarms. I'm not familiar with other makes.

 

@shifty` Thanks for the reply with additional info, believe me, I do not talk smack about high millage autos, as my wife asked me about a 2006 toyota tundra truck a few days before she bought it, as she did not say she was buying it or the millage. I told her it is a great auto from toyota if it has been maintained and runs and drives, ALSO found repair receipts in the truck from 2022 with a 999.72 bill, replaced balljoints and front wheel hub assembly .

Now for the good stuff, these are pics of the unit still installed and functional, it is a aftermarket setup so it is almost plug and play except for a few t spade wire splices ( these are further up behind the fuse block no good pic yet) .



This image is of the plug and play main harness, index and thumb, I unpluged and pluged the fatory plug into the factory plug-in at ignition switch (I have a bad back and 2 vertibre broken in neck so I did not get all twisty looking



I am curious to what aftermarket manufactor this setup is from as it does work, is simple to install from what I see personally.

As for the sand in floor board we are in central Arkansas where there is red clay and sand used to extract crystals when they are very big to cut them down before transport, but yes there is small rust coating but nothing I see is a bad deal here.

 

Ok, I was wrong. It appears it is a SECURIKEY+ system, which would've been ported by the regional entity, or the dealer. It looks almost as if that last picture, it's two of the same wire plugs, which is interesting.

Anyway, I'm attaching the schematic. If I were you, I'd remove it fully. Aftermarket alarms tend to flake out after 10-15 years. Some last longer, but ... they're not made to OEM quality standards by any stretch.

 

Thanks @shifty` I will remove it completely and solder/heat shrink any cut wires back to factory for sure! And thanks for the schematic! .

It is very hot where I live ( as of todays weather) I have to take breaks so I will follow up on the end results and more pics as I get deeper so that if anyone comes across this thread they will have it all

PS - For your own safety, please confirm they used OEM lower ball joints. This is not a "nice to have". It's a legitimate safety warning. Aftermarket joints DO NOT last. Dealer would've/should've installed OEM, but it's not always guaranteed. If you see zerks on the joint, it's not OEM. If the boot is any color other than black, it's not OEM.

 

Hot here today too! "Feels like" temps of 104° today. Wild.

And yeah, if you're anywhere in the SW USA or Texas, a lot of trucks got the SECURIKEY+ or KARR systems installed. We sometimes see similar on Toyotas rolled out by SET (Southeast Toyota group). I reckon you must've known that based on your 1st reply in this thread!

 

Yes I sure will check the info in the receipt as I read about the ball joints and such before I registered to here. I will do oil change and such and go through the brake system as a precaution!

EDIT - I actually told my wife after I looked at the toy that she may have bought a gem and did not know it, but she paid cash and trade not 700.00 but 1,100.00 for it.

 

She probably did find a gem....she's worth keeping!

While this is a Tacoma 'Gulf States Alarm system how to, the items you're showing in your second post, are easily removed and should pertain to even your Tundra.

Still a great price, good find!
