So I have recently progressed from possessing a car where theft would involve refitting an axle and fuel tank to a car where you'd just need to know what wires to twist and you're off.

I've got a LONG list (seemingly infinite at this stage) of jobs I'd like to do on the Panda but really security has got to be high on this list. I want to go on adventures in the car and I don't want the freedom of the road to be watered down by worry about where I can or can't park the car, or to a lesser extent what I can leave in it.

So two things to cover, some kind of secure storage (given if I upgrade the locks windows will be smashed or doors bent) and some form of immobiliser. For the minute I'll start with the immobiliser. Electrics are very much my weakness, I just about understand a multi-meter and though I sort of know what they mean complicated wiring diagrams scare me, I'm starting this thread for a few reasons, help for me being one, social being two and thirdly hopefully by bouncing ideas around it might help others too!

The Panda is great as it is so simple to work on but I can't help but think that this would also make it easy to nick for the same reasons. I'm not kidding myself that some career criminal is going to show up hot wire it and ship if abroad for vast sums of money;), more likely some ned/chav/scrote (call them what you will) will see something easy to nick and go for a joy ride (or even a cheap alternative to a taxi home).

I've searched the forum regards immobilisers and generally the threads that have come up have been people removing the pesky immobilisers when upgrading to 16v fire engines. I really do not want to add a possible electrical gremlin but figured if I wired in a simple toggle switch somewhere it would be unlikely to cause problems but for a thief who does not know about it, it would be time consuming to discover.

I've heard of people removing relays/cables from under the bonnet to this end but a) you'd have to get under the bonnet to do this, which is obvious when parking and a pain and b) if the thief has any idea what they are doing it may well be obvious what the issue is.

I could wire the switch on the ignition, starter motor or fuel pump. My initial thought would be the fuel pump for several reasons:
-Ignition circuit handles higher volts, more likely to cause issues and switch would need to be strong (or wire in a relay which adds complication and potential issues). Also if starter and fuel was working the engine could become flooded and if hydrolocked (or whatever it is called), damage eg bent conrod could be caused.
-By stopping the starter motor the theif would know something was up (as with ignition really) and could easily bump start the car anyway.
-Power to fuel pump could easily (I assume) have a switch put on it, it runs the length of the car so plenty of places the wires could be cut so hard to locate and options available. When attempting to start the car it would not be obvious it was immobilised, also the potential theif would sit there cranking the starter drawing attention to themselves and I hope give up.

So that's thoughts so far, welcome ideas and opinions ranging from what I'm looking at is pointless to the other end of the scale people who already have a system in place like this. Clearly no one will want to show photo's of where the switches are hidden and how to start their cars on a public forum but pointers like what colour wire to work on for the fuel pump greatly appreciated! Also any issues I might be creating for myself!


Cheers again

Ok to things that thrives hate are time and noise for £15 a classic car battery isolator just run the negative / earth through it It will switch of all power to all systems Fitted one to my daughters beetle under the rear seat panda one would easily fitted under the hammock dash !!!

Or if you wish fit it in the starter motor line but that won't stop it being bumped started
The traditional crook lock is very visible and effective it will prevent further damage
Remember it takes 5 secs to get through the door lock then the lock barrel 30 secs.
There loads of alarms remote for £20
Motion sensor connected to a sound bomb in the cabin
Most alarms ( look for a drop
In voltage of the battery ) which then go to alarm state when any light or switch is operated

This is a great collection of ideas. I have considered the kill switch on the negative before (carburettor'd engine) but I like the fuel pump option even more, especially if you were to put in a 3 pin switch and swap the fuel pump live straight to he horn when "immobilised" :D

An old trick from last century was to remove the rotor arm from the distributor. But that needs bonnet opened and a few moments of work. A real pain, especially if raining.

If it is fuel injected, a switch in the fuel pump feed is likely to be very effective. Difficult to find and to by-pass, most thieves will move on.

If carburetted, you'll have a mechanical fuel pump, so fitting a tap in the line is much more difficult and potentially a leak point. The battery earth cable switch might be best there.

If doing anything invisible, also consider the krooklok as well as a visible deterrent. An invisible immobiliser will not stop the hassle of broken windows and ignition switch.

Leave the inside of the car filthy, half-eaten sandwiches with mould on should act as a great deterrent. To you as well sadly.

A simple notice in the window stating 'broken down' might work.
 
Cam you make life simple
i used to do it in one of my old cars but cant for the life of me remember which one!!

does the spi panda have fuse for fuel pump under dash roll?

if it did it would be ideal, invisible to anyone watching, simple reach below the dash roll and place it into servizi slot (wont lose it by taking it with you) then lock doors and possibly crook lock. the enemy of the car opportunist is noise and time taken, the noise and time these 3 steps would take would deter and ultimately stop someone stealing your car for an opportunistic joy ride. it doesnt stop damage of course but at least its not going anywhere
 
Alarm fitted to all systems working on volt drop best option along with isolator and crook lock to
keep the alarm live by feeding it before the isolator switch
Or get a jack Russell
 
Alarms are usually only of value of the owner hears it. Everyone else just cusses.

In the eighties, when car theft reached a peak, aftermarket alarms were often rubbish, and it became a frequent occurrence to hear random alarms, which became annoying. House alarms also fall into this trap.
Now, when we hear an alarm, instead of thinking "Someone's property is being attacked, can I help or call for help", we instead think "Oh! another ****** alarm".
 
Loads of class ideas on here, I'm working today but day off tomorrow so will be able to have a proper look through them all(y).
 
I use a Stoplock steering wheel lock, a visible deterrent like that will put thieves off as they know they won't be able to drive off with that in the way, and they won't be able to cut through it without getting noticed. The harder the target, the less they'll tend to go for it, so a visible deterrent is great in my opinion :)
 
Normally not discussed in public as ideas get easy intercepted by thieves doing research.


Like the thought but we're only giving advice the type of person
Who would steal is most unlikely to research the panda classic section of ff for a soft target
It's so easy to steal the keys of a 70000 Range Rover and make off to Nigeria with it ,

I had a mate parting with his mk1 escorts over night from back garden secured garage, how? fully exposed on-line, easy to be sussed out , down to party night widly brodscasted and discussed on FB.
 
best anti theft, pull the ECU if its injection. i have done it on fallout in the past when i had no door locks.

a few simple things like unplugging differant things under the bonnet, inside the car you could make a simple switch that turns on a relay... that turns on the main ignition live. going to the key switch.. Fallout now has a nice alarm fitted (Toad AI606) which can be found on scrap cars in scrap yards. they support all kinds of things and make it very easy to add central locking to the doors. (which is so nice)

Ah now I see FB whole life exposure !!!
 
Ooh, central locking. Is that not just showing off?next someone will want a classic panda with power steering... And heated seats...and air con. I am sure there are a few people that would manage too

Yes Keyless option on central locking
A least the lock couldn't be pulled. If all removed could be the way forward !!!
