Nissan keyfob information

tedted

the battery for my car is a vl2020 which is rechargeable by the vehicle i think some fords also use the same battery but not sure.rarely the battery goes down but if it does they want to sell you a new fob but it can be changed if you are ok wi a soldering iron and stanley knives

quartzz

Nasqueron - sure. I'm just guessing from my fathers story that it's possible some high end car manufacturers might have done the maths, and worked out that if they locked customers into a £100 keyfob change (for eg), they could afford to produce (well, it would be getting an existing battery firm to tweak a design, the car manufacturer wouldn't have their own battery manufacturing plant) their own battery and for the proprietary design to pay for itself in eg 10 years (or something). or not - who knows

Goudy - modern tech, eh. no wonder the people who provide the power like new tech which uses more of it

tedted - sure. I mean, would you want to risk locking yourself out of your car for the sake of £20? and a stanley knife that slips and a soldering iron which bridges some contacts it shouldn't :[]

This seems to be going around in circles. For the Audi TT they used the 6120 battery for the older cars with flip keys. When they moved to smart keys they used 2032 batteries. There are no proriatory batteries in Audi key fobs. If the TT in question was from 2018 as stated it will be the smart key and would have had a 2032 battery in it.

Your father would appear to have miss understood something or was told a pack of lies by the dealer.

And Lamborghini use Audi key bob internals with the same 2032 batteries in them as they are both owned by the VAG group.

quartzz ive only changed three of these batteries in those fobs and you use the manual key to get in and the fob will still the car so not really a problem

Hi. It isn't difficult. It (may) make financial sense for a high-end car manufacturer to use proprietary components (keyfob, wing mirror, foot mats, rear windscreen wiper), with the business plan of being able to charge customers more for their upkeep, and recouping their costs within a planned duration. I'm sure the rest of your comment is valid. My example of Lambhorgini was a randomly chosen supercar brand. As I (think) I previously said - it could just be that the batt used in that keyfob, isn't as well known as a standard 2032

tedted - indeed. I'm just thinking you (anyone) don't want to bodge a fob which contains some kind of transponder code, and that magic unlock button ends up not being a magic button

so anyway. yeah. save yourself £5, some petrol and a trip to the garage on a Nissan keyfob change

There isn't a snowball's chance in hell Audi or anyone else have their own special manufacturing plant of batteries just for keyfobs, the R&D costs alone would be astronomically higher than they'd get from the revenue before you look at the production line and there's always someone who will clone it to undercut.

If you wanted revenue like this, you'd simply design the fob so it didn't store data if the battery was disconnected (e.g. not using a capacitor to briefly store power to do this, or a solid state memory chip) and force people to come into the garage to get the battery done every couple of years. Using an obscure battery might be an option e.g. the CR2025 mine uses aren't as common as CR2032, or you could use something like the LR44 that my bike power meters use which you have to buy online rather than a supermarket to make it harder for people. Or you could make the fob with something like torx fittings that aren't as commonly held, to make it hard to get into. All of which can be solved easily enough hence making your own battery is pointless.

A long lasting battery from back in the day is simply because there was less tech used and the key was only needed for remote unlocking so less use of the battery

paragraph one - yes....this is what I said. It's conceivable that a high-end car manufacturer might have contracts set up with an existing production facility to create products specific for that car. production floors I have worked on have certainly had third party deals with all sorts of other companies to produce parts that only one company uses

the second - yep. indeed. radio's used to just have tuner for example. now they have LCD displays and "other stuff"

fwiiw, his Audi is 67 reg, so it's the "less common than CR2032" item by the looks of it

Perfectly reasonable for a £13,000 instrument cluster. By the time you designed, manufactured and stocked a custom battery - you probably wouldn’t break even at £100 a go.  There are consumer products using customised lithium batteries but they sell in their millions - Audi only sold about 600,000 TTs over the entire product lifetime.

Nope, 2017 Audi TT uses the same fob as my 2019 Audi A5 and it is a 2032 battery and very common. Just looked at the owners manual to confirm.

The fob casing itself, along with the board will be proprietary to the manufacturer. However the manufacturer of the case and board will be outsourced to a general manufacturer and standard chips and batteries will be used.

It's a 2017 reg. remind me again what we're talking about?
