Default Re: Car Air conditioner electronic lock or remote

So immobilizer is out, handing keys is out.
What remains is buying a Xylo (!!), trying a bike alarm system or a 12V DC remote system.

On a lighter note, buy yourself a Xylo, which has a feature to infer how many kms where driven with AC and how many without AC.

Default Re: Don't want the driver using air-conditioner in my absence

We have not directly asked if he uses the AC when we are not there, but we think we can indicate to him that the fuel efficiency is not as before, so that he knows we at least have an eye on that. Probably that will help change his attitude. On the other hand, we cannot be really sure he is using the AC, unless we put a hidden camera or some other gadget in the car. Maybe we ourselves are using the AC too much ! Handing duplicate key is out of question.

Anything which makes the driver to feel that you don't trust him is a bad idea.
If you start handing a duplicate key every time you get down, any individual with some self respect will not stay. It will only the spoil the relationship.

I think you are right, better keep things over the table. Just installing the system may lead to his trying to manipulate it.
Of course, he will know something has changed, when the AC works only when one of us is in the car.
thanks.

Why don't you talk to him that you are finding the fuel efficiency low these days and ask him if he is using the A/C on idle. Let him know that it is not good for the car and your pocket. As a further step, follow what GTO pointed out - "BTW, monitor your fuel efficiency on a full tank to full tank basis. Hold your driver responsible if it falls too low."



Why? Won't the driver think why the A/C works only when saab is inside the car? If talking to him do not work out, better let him know that you will be forced to install a sort of control - mechanical or electronic as suggested in above posts. He has to know why he is punished, otherwise he can try tinkering with the control, thinking since you did not speak to him about it, he also not going to speak about overcoming it.
That is worth a try, but usually one of us would be with the car while petrol is filled up.

You are right, it would at least give some evidence that he is using the AC. Let me see if an electrician can install such a device, once I find one.

Thanks for the details. Any idea about how much current amperage a car AC has ? Or probably use same amperage for heavy duty relay and wires, as used for the main AC switch - that should be mentioned in some spare parts list.

So, using bike Central lock System as such to switch A/C on is bound to cause electrical problems. Use Havell's/Finolex HRFR cables of 2sq mm or more, in addition to the relay for this application .

I might sound too philosophical, but exchanging keys would look "inhuman". Most of us face this problem and one suggestion is to take your driver to a better place for him to wait. Say if you are visiting a mall ask him to also take a look around and simultaneously explain him the harmful effects of the A/c being switched on in a stationary car.

Ideally the driver must also love the car, but one has to be lucky to get such a person.

I suggest to better keep things simple and ask him if he uses AC and if he does tell him not to use it.
