Car- GLS 2009.
Someone recently got into the "secure" parking lot of my building and tried to access my car via the only lock cylinder(driver door). Looks like they used a screwdriver or some other brute force method. Not sure what they were going for, but the lock is now totally deformed and unusable. I'm worried they might come back and try to steal my car given the vehicle was totally empty at the time and the only obvious conclusion is that they were after the car. I'm considering removing the starter fuse as well as other vital fuses/relays to temporarily make it impossible for the car to start. Please advise. Greatly appreciate any tips.
Also looking for a good way to seal the new gap between the housing of the lock cylinder and door so water doesn't seep inside the door and cause issues.

Many years ago my brother put a toggle switch in his cars. It was not visible sitting in the car but you could reach under the dash to turnit off or on. He just put one of the ignition wires through thr switch.

You'd need a wiring diagram to know what wire but it should work as no juice got to the ignition.

Thank you. I like the toggle switch idea, but car/motorcycle theft is relentless in my city and has only gotten worse in my lifetime. I used to remove the ignition wires from my pickup truck. The wires are a little harder to access on the sonata, but I would like a similair way to disable it without needing to remove the battery after every time I drive it!

 

A bright colored (yellow) club bar will deter 90% of thugs. But won't keep them from breaking a window to check for items. I like to leave my glovebox open to "show" there's nothing in there. For the lock, try clear all weather silicone.

 

I bought a bright yellow club yesterday. Now I have one going from the brake to the steering wheel as well as the yellow one on the wheel. Going to try the silicone. Hoping when I replace the lock cylinder that the housing returns to its' normal position as the door surface looks undamaged!

 

If it were me I would be disabling one of the relays. Starter or engine control. Engine control would knock it all out. Use some 18 ga twin conductor like speaker wire. And loop the #86 wire, ECU ground control for relay coil through a switch.

The ignition switch wires carry quite a bit of current so if you use them be sure to stay the same amp rating.

 

I think long term I will do something like that, but I don't have any spare time with work currently so I need to do it quick and dirty.

 

Looks pretty ugly on the car but it can be affective lol

momentary switch on the trigger wire on the starter solenoid so when you turn your key forward to crank you also have to push in the momentary switch, of course hide it, easier than having to put a fuse or relay in every time. Also any compentant thief would just swap a fuse or relay over to the missing one anyways, don't need a wiper fuse or relay to start the car

 

Yeah, I might end up pulling all the relays just to avoid that issue of being able to switch to a non-vital one.

 

Pull the relay for the starter.

 

I pulled the starter relay and the fuel pump relay. Thank you

 

As someone once said "drive a manual and they don't know how to drive it" but of course thats rediculous. I have a diagram of a simple setup where you have to sit a magnet on top to operate the fuel pump only when starting. You hide the other part of the switching unit under an easily accable plastic panel. Once started you can put the magnet in your pocket and continue driving till the next start. I'll have a look for it tomorrow and post it up. It does work.

 

Yeah I wish that was the case. My toyota truck(manual) was stolen for 3 months and totally trashed. Even had a club on it at the time, but this was before I started pulling the plug and coil wires. The sawed through my steering wheel to get the club off. We have a very high population of low life's and a very thinly spread police force that doesn't really enforce anything vehicle related unless someone is actively shooting from a car.

That sounds like a neat mod to be able to use a magnet to start the car. Reminds me of those hidden drawers in furniture that are also activated by a magnet.

 

This is the circuit for a magnetic operated fuel pump switch.
The reed switch is just a simple on/off alarm switch used on windows and doors. It has to be wired up to the contacts marked NO.
The relay is readily available from a electronics part supplier. I can post a pic and part number but can't guarantee they all use the same number.
The way it works is you palce the magnetic part of the reed switch over the reed switch which is hidden behind a plastic panel.
This powers up the relay and you can start the car. You can then remove the magnet and the car will keep running till you turn the key off and will not start till the procedure with the magnet is done again.
Really handy if someone tries to snatch your car from you. They can have the keys but as long as you have the magnet they can't start the car.

 

Sorry I made an error with the relay wiring.
This is correct.
This is the relay.
