Firstly, appologise for wrong forum - I posted here since there's no '2018/2019' Cmax forum


Some background - been a C-Max owner since 2008 (titanium model) but thought I'll trade in the old reliable (had same car for 10years) for a newer model - which is also a Titanium model (I'm currently waiting for delivery)



Of course there's been a LOT of changes in those 10 years, one of which is 'keyless entry' & recently I've been reading a lot about how easy it is for car thiefs can get into keyless entry cars so naturally been looking at any preventative methods available


Basically found - old fashion steering wheel locks (which sort of defeats the 'keyless' aspect) & some form of blocking pouch/wallet for the keyfob (or wrap it up in tinfoil)


I'm planning to get a steering wheel lock (just not sure which one just yet) but personally I HATE the idea of sticking the fob inside a wallet & having to carry that around with me along with everything else (I already have to carry a wallet, various keys for work, a seperate ID card holder & usually a mobile phone & when I'm not wearing a coat means everything is stuffed into trouser pockets)



Now I've been looking for any alternative 'hacks' that could disable the keyless entry fob until I want it to work, but the ones I've seen involve stuff like taking the fuse out of the fuse box, however after finding a [ame="https://www.youtube.com/watch?v=ofRVyP4PAzg"]Youttube video on 'changing battery'[/ame] in the fob got me thinking that MAYBE there is a way of hacking the fob

Here's my idea & I'm wondering if anyone has ever thought of this, tried this perhaps - or would it cause some other problem (like with battery disconnected would the fob lose it's memory ?)

Hopefully the picture attach explains it, but here's the idea

1: Solder a couple of thin wires to the copper pad on circuit board & the '-' (negative) contacts on battery holder

2: solder the other ends to a single pole toggle switch (not sure if you can even GET a switch small enough although some circuit board have 'DIP' switches which are pretty small ~9mm x 5mm)
3: Place some insulated material between the copper pad on circuit board & the battery contacts to prevent these from touching


The idea is

- with the switch turned 'off' the battery is not connected & so the key fob can't transmit it's signal
- Turn the toggle switch 'on' then allows the battery to connect which in turns allows the fob to transmit


So my question is - would this work ??

I admit I would be a little scared to attempt this on a brand new key fob (I ASSUME I get 2 'keys'/fobs with the car) but maybe there's someone out there who thought the same way as I have & tried it out (I did search forums but had no success)



Thanks for any advice in advance

That switch would work the trouble is the key would lose its code after a few minutes without battery.
Personally, I'd leave it alone most cars are going keyless now I think after a while you will get used to it.

Stoplock Pro .

The Faraday bags are more about car theft from home as the tealeaf's amplify the signal standing outside a property when car is on a driveway .

@nighthawk: thanks for that info. I wasn't sure if the fob had an EEPROM or not (which usually are not affected by lose of power). Knowing that means I won't even think about the modification

@gazwould: the stoplock pro is one of the ones I've been looking at (the other is a monojoy) - mainly because online reviews show these were the hardest to break (~5mins using tools)
As for 'when at home' I'm planning to have a small lidded tin box in the drawer where I usually keep my work keys for the fob (cheaper and easier to dump them in a box instead of faffing around with pouches)

- I was thinking more of when I'm out-&-about since I remember a Top Gear episode where Clarkson moved 'Hampsters' car out into middle of a freeway because it was keyless start (I think they were in a cafe)

Now that I know the switch idea won't work I do have another idea of making a small 'cover' that slips over just the fob (basically a smaller version of the pouches) that you can slip up to use, then pull down to protect like a sock

The only problem I can think off is - does the whole fob need to be covered to prevent signal leakage or can I get away with the bottom edge still exposed (I think it'll need to be fully enclosed)
Guess I'll find out when I eventually get the car in (hopefully) a couple of weeks

Once again thanks for the info

You're more than welcome, and I would recommend Autoloc 2000 that's what I used on my focus RS small neat looks good when it's on and impregnable but if you do get one hide a spare key somewhere in the car because if you lose your keys they have to be ordered by number.

Scumbags can buy tech off ebay that picks up the signals from the key while your asleep or in a car park then drive off in seconds no need to smash glass or force entry.

Can’t say I’ve ever known or met anyone who has had their car stolen this way.
I have - 3 people in fact


1 caught someone opening the car door when they went back because they forgotten something
1 had stuff taken out of their car (they were lucky to have steering wheel lock)

The 3rd had car stolen (no steering wheel lock) but was lucky to get it recovered but there was no sign of forced entry



If you go to Youtube & search for 'keyless entry theft CNN' - there's a video from police that shows how it's done



@Nighthawk - googled that one, but personally I don't like 'full'/'half covered' steering wheel locks mainly because they are bulky hence why I am considering the Stoplock Pro or the Monojoy 2018 model


Looking at reviews online these two (along with the full steering wheel DiskLok) were the hardest to break open (over 5mins according to some reviews)

I like the idea of the compact Monojoy but would've liked it with a HiVis yellow arm to it (hoping thieves see it more clearly), while the Stoplock is yellow but could be slightly cumbersome lifting it over onto back seat when I have a passenger

That's not good I guess the answer is to have a socket for the key to go into before it will start something like the BMW and mercs uses on non-keyless.
But I guess it won't be long before we have fingerprint readers on the car door handles and start buttons?

I would think if a thief had an eye on a car with a steering lock no matter how good it is he would simply hacksaw the steering wheel itself then push the lock out through the gap.

To all - thanks for the advice...
You have really decreased my worries about Keyless Entry systems..... NOT !!! ;)

I would think if a thief had an eye on a car with a steering lock no matter how good it is he would simply hacksaw the steering wheel itself then push the lock out through the gap.
This is true - found a video that shows how easy it is for most steering wheel locks to get off by cutting the steering wheel - however the Stoplok Pro may be more difficult than the 'single hook' ones..AFAI can see to get this one off the thief would need to cut in 3 places to remove the lock (each side of the lock hooks & the spoke underneath) which may be difficult since it's covered by the lock cover

Yes that is very true when I had my RS focus the only steering lock what the insurance would approve and give a discount on was this
These types of steering locks do seem to be the most efficient (The Disklock seems better) at detering thieves, the problem is IMHO they're too cumbersome.. having to remove a large 'disk' each time I get into car & finding somewhere to store it (especially when I have a passenger which would mean lifting over seat to dump on back seat). I think I would be less inclined to fit it each time I get out of the car - a Stoplok Pro seems the 'next best thing' (according to reviews) since it's not so big/wide


I have the following plan to reduce the risk (& hopefully reduce my worries as well)

1) Get a metal box (with lid) to place in the drawer I usually keep my keys in (which is ~10 feet away from front of house - hopefully far enough) - Probably find one in a 'poundstore' or something - this means I get home, drop keys into tin & close lid.

2) Get a Stoplok Pro - since this is one of the few that took a security firm over 5mins to break into. It's not as bulky as a disklock & may be more managable to store.

3) Get a RFID pouch for when I'm out & about. Most of the ones I've seen are quite big, so I have plans to rip one up & re-use the RFID fabric to make a new smaller version that just fits over the fob like a sock -with a chain through base of sock so you can slip it up to allow fob to work then slip it back down when walking away

4) Stick some fake 'fitted with GPS system' stickers on windows (Not necessarly these - even I can tell it's a fake due to the barcode not being recognised, maybe these ??)

My 'research' does show that no matter what you use - a determined thief will steal your car but an 'opportunist' thief may have second thoughts.

Doesn't stop the car getting broke into but may stop it getting driven away

What do you think ? good plan or can you suggest something else ?

There were in the 80's-90's a couple of aftermarket units that may still offer some help against theft, one was a keypad that was linked into the ignition circuit, 4 numbers, get it wrong 3 times and off goes the alarm. The other was a stealth switch that was a control box mounted hidden connected to ignition and started circuits and a flat ribbon cable with a flat push button on the end, you fed the button under the carpets to a place you could push it, say on the side of the seat by the park brake. You had 10secs after ign on to press the button or it just locked out until you retried ign on.
Neither will stop them hitching it onto a dolly and towing it away though.

LOL - funny enough I actually remember my Brother doing a cheap-&-Cheerful DIY version of this on one of his cars (I think it was a cortina)
IIRC all he did was buy a 'standard' Ford toggle switch that fitted into a spare slot on the dashboard/centre console where a switch would 'normally' be IF the car had that feature installed (for example Electric windows) which in turn was connected to the Ignition circuit


You had to turn this switch on before turning the ignition to allow it to turn over...



...Ah those were the days when anyone could DIY things without needing a degree in Car electronics XD

When test driving my escort 1600 ghia in 1980 the salesman bought a can of fuel with him He said it was a bit low. Sure enough a few miles in it ran out so while he refilled it from the can I fiddled with the switches. It would not start at all. I thought no way am I buying this. By sheer good fortune the driver of the breakdown van which came for us started laughing. Youv'e hit the swith haven't you he said. I played with a few while he was refilling I said. The breakdown driver himself had fitted a engine cut out switch on the dash for his mate the same car I was testing. Click fastest repair in the world . I bought the car.

I had the same thoughts about the keyless entry and stop-start, not sure about messing with the fob though. Has anybody got a wiring diagram of the stop-start circuit they could take a pic of and post? I realise nothing will be straight forward as whatever I do will probably set off all sorts of fault codes in the car.
