Title: Security
Post by: guest13757 on November 25, 2024, 08:07:09 PM
Do you “super lock” the doors of your Hybrid Jazz?  And do you use a key fob Faraday box?

No, I don't "super lock" on a regular basis (only if I know the car will be sitting idle for more than a week).

I do, however, regularly switch off the key fob (you can do this by pressing both buttons for about three seconds until the red LED flashes twice).

This keeps the key fob from transmitting any signals until you press any key again.
You cannot unlock the car with a thusly disabled key fob (and I think it may prolong the key fob's battery life at the same time) - wow! another 50ç saved!  ;D

Moreover, I keep the key fob in a padded old Smint box which fits it perfectly and prevents from inadvertent key presses (which would reactivate the transmitter) plus is capable of shielding even an active key fob!

The current Smint box is somewhat longer, wider and flater but is still capable of holding (and shielding!) a Honda key fob but it will need different padding.

I keep my key in a metal minitures whisky box. It is all metal and totally shields the key. I have tested it, and it works.

Always double lock as I understand it shuts down all non required systems so helps the 12v battery

Also turn off the key to prevent any relay attack

We also always double lock and switch off the key.

I don’t quite understand this discussion.

Firstly, why would you not deadlock your car? It’s easy to do, and (AFAIK) there’s no downside. So why not?

Secondly, keyless entry is sold on the basis that it’s hands-free, you just have to have the key on your person. And now I see people putting the key away in metal boxes, or having to disable it, all of which negates the hands-free functionality. Seems easier to me to just have the system whereby you push a button on the key to unlock/lock the car … or maybe manufacturers have decided on your behalf that you don’t want to do that so you don’t have any choice?

My Mk3 doesn’t have keyless entry, so maybe I just don’t see the benefits.

I was quite happy just pressing a fob button on my 9G Civic, never had a problem

Now I have the keyless Jazz MK4 I'm aware of relay theft so indoors I disable the key(s), when I'm out I just leave the fob in my pocket on the basis I'm not close enough for a relay

I also don't see the attraction of keyless as with my Civic I pressed the unlock button when I was within range and it was unlocked when I got to it

I only keep the key in a metal box when I am not using g it. Once I take it out I use it as keyless. Which works very well.

@Worthingmike
Why would you keep the key in a metal box when you are not using it? Why not simply switch it off? And the added benefit: the battery will last a little longer.

I put the key in a Faraday bag (its just its place when not in use) in the kitchen, which is the furthest room from the driveway.. and where we keep all the other household keys.
I also use a Stoplock pro elite on the steering wheel... at home and everywhere I go.
I think the Jazz is less desirable to exporting/ringing thieves than the high end marques, but there may come a time when its parts and components become valuable. Already we are seeing bonnets/wings/bumpers/sensors/electrical parts stripped in the street from some models.. and no switching off the fob/Faraday bag/Stoplock is going to prevent that.

I put  the 'working'  key in a faraday pouch  when away from the car .  The spare is permanently disabled by double button press.  We dont have 'his and hers' keys. We always share  the same key, the spare remains as the spare.

TBH I cant be bothered to switch it off every time using double buttons.  Putting it into its snug little sleeping bag  keeps it protected and clean when in a pocket or bag . And leaves no doubt whether we remembered to switch it off. .   Battery life may be shorter  but less chance  of button malfunction due to frequent  use or getting bunged up with grease from your fingers and dirt.  (Which happened  with my 14 year old car keys, and TV remote )

I have read that some faraday pouches are not 100% effective  but I have tested mine and it seems to work.

I have found that switching off does not always work if you don't push the two buttons at exactly the same time.  I find it easy to just drop the keys in the box.

I turn the fob off and keep it in a faraday pouch. As I am often in London I also put a steering to pedal security clamp on.

If someone wants it they will get in sometime but anything goes just to make it a bit more difficult. Thankfully as I was told by a friend “no one in their right mind would steal a jazz only people over 85” bit cheeky but it gave me a laugh.

Aye, it would hardly be a quick getaway  ;)

I tend to switch the Jazz key off, but the E key was a year earlier and does not have the switch off function so keep it in a snug faraday pouch in the pocket when out and about.

I keep a stock of pouches that suit because they do wear out every 6 month or so, you need to wave it in front of the door occasionally before breaking the velcro, when worn the handle will pop out even with the bag still closed showing the effectiveness of the bag has stopped.

I agree the security hassle of keyless is just not worth it. The number of times your hands are full and you want the door unlocked automatically is minimal (and even then you need to empty a hand to open the door), and reaching into your pocket to click a button was hardly a problem. Replacing a system where you had to press a button, to a system where you don't have to press the button but anyone with a piece of wireless kit you can buy straight off the internet can have full control of your car within a few seconds was just crazy, and the car theft statistics prove it.

But who would suspect an 85 year old with a relay scanner disguised as a hearing aid?  For some thats a pension plan ;D

I am trying to keep up with all this security lark.. ;D
I am getting confused about this keyless access system…* not available on all models it says in the handbook.

So is this model keyless? I mean to say I use the key buttons to lock/ unlock my,new to me, Mk 4 Jazz…

Also , and I quote “ communication between the keyless remote and the vehicle consumes the keyless remotes battery”
“ battery life is about 2 years…”

So my question is,does this apply to my car?..

And if so how do I replace the battery in the key fob? Handbook doesn’t seem to say,unless I just can’t find it?
And where to buy and how much money?

I am worried about this as in 2 years time I could be sitting in the car but the battery is dead and so the car will not start?
Is that correct?

And yes,I am an old bugger :-*

If your model is keyless then with the fob in your pocket, no buttons pressed, the drivers door opens when you pull the handle

To change the fob battery is easy and is covered in the manual

My 72 SR is NOT keyless entry (but is keyless start - once drove home with keys in boot)

I had to change my battery recently after 3 years.
Instructions are in book but hard to find. Under Remote Transmitter Care, P576
Hard to prise it open, but managed it (took longer to find a coin...)
Normal Duracell CR2032 battery

CR2032 batteries, widely available.  But buy good quality.  Cheapo ones from discount stores dont last long.

Dont worry.  The car gives plenty of advance warning  the key battery is getting low. Probably several days more use.  The symbol is large ,difficult to ignore and its obvious what it means.     If you're worried just keep a spare CR2032 battery in the car.  If necessary   you can unlock the drivers door using the built in key blade (see illustration in twf7's post )  You can also use this blade to prise  open the key (or a coin) to change the battery.

Aha! That explains it a little. Thanks. Mine is a 2023 SR so not keyless :'(..no wonder. Thought I was going crazy.
Anyway,I only have 442 pages in my handbook…I looked where you said and it explains locking/unlocking but nothing about the battery and access to it. How very strange.?

Rather important methinks that this vital battery doesn’t seem to be worth a mention. It mentions life of battery but not what it is and how to access it!
I shouldn’t have to rely on this (wonderful );forum

Thanks all

I’m more worried about the car not starting. I know I can open the door with the ‘hidden’ key.Thanks

If you have the online/pdf manual, try searching for "remote transmitter"

The car will sense when your key battery is low and give a dashboard warning to change the battery well ahead of when it no longer works.

I find it easier using the on line version of the manual.  Its searchable . Its similar to the paper  manual  but page numbers differ slightly so I think there is more info .

There is  also a separate Sat Nav  manual on line for the "Here" system in my My24 car. This is definitely more detailed than the sat nav info in the paper manual. 

Also beware that  the manuals tend to give info in two columns. One appears to be the main information while you might skip over the second thinking its just notes.  But it contains some essential details.  (such as how to turn off the key transmissions by pressing both buttons)

Very useful thanks. A technician did actually show me today also.

Regarding screen washer jets on my car: Dealer has looked and decided to replace,under warranty,all 3 jets.
The rear one was completely blocked with crap and the front ones not directing the water properly!

And the car is only just over 18 months old so a little disappointing to say the least.

Disappointing yes, but depends on the previous owner(s) using a decent quality screenwash fluid
