Keyless Major Major Flaw!!!

My Renault RS225 had keyless entry, but you still needed to 'double tap' the handle sensor to lock it.

But what if one cold morning I went to the car, heater on then went in to house with key, engine running, thief simply gets in car and drives off????

How is it any more of a security risk than leaving a car running with the keys in the ignition?

In fact it might be only a little better with keyless, but at least they don't get a whole bunch of house keys with the car when it's nicked, & they'll struggke to restart the car when they eventually turn it off.

My thoughts exactly :)

What if you just unlocked the car and started loading shopping in, then someone gets in and gets away with it? Very very unlikely but could happen. That's why I don't like these keyless things

I think that's impossible because the key has to be inside the car to start the engine. The idea is you leave your key in your pocket and this sort of thing can't happen.

It's a great thing to have when you have young children, especially if your carrying a child to the car that is asleep and it's p*****g rain. The last thing you want to be doing is poking around in your pockets holding a child in the rain. I must admit Renault keyless is away better than the one on the Ford who seem to have done a half a***d job

I'd be interested to know what improvements Renault have made, is it just the auto locking because I thought the Fiestas do that after a while? At least they do if you don't open the door, maybe not if you do open it, seems like a design flaw if that's the case. Apart from that I haven't had any issues with it, I haven't used any other key free cars but this seems like a great system to me.

You won't "hotwire" any of these cars with an immobiliser, but you can brick the window plug a key reader into the OBD port, get the coding, and program a new key there and then and bye bye car, thieves these days stand no chance of nicking a mk3 fiesta due to skill shortages, all new cars are very easy using the method above.

Google Audi rs4 stolen is 30 seconds, easy peasy.

I saw this on watchdog, I might have to read up on it, but I'd be interested to know if most new cars (especially Fiestas) are vulnerable in the same way. If so the manufacturers have screwed up massively, with the amount of security testing these systems go through it would take some real stupidity to get it so wrong. Why they would design the OBD port to have access to the key codes is beyond me, they're basically inviting people to steal the cars.

While the end result is the same, what I've read seems to say that the issue is with manufacturers making the specialist kit needed to access the car's locking systems through the OBD port available to dealers and the like. Possibly they're compelled to do this for their franchised dealers, and perhaps to wider dealers in compliance with Block Exemption laws.

Course once the kit gets out into the big wide world there's absolutely no control on anyone getting their hands on it and using it for dishonest purposes or making their own devices. Also your general techie-geek can turn around work-arounds for security systems a hell of a lot quicker than the manufacturers can react with changes to counter the known flaws at any particular time.

Any lock made by man can be defeated by man.

Change 'lock' to 'thing'!
