How is the battery changed in the remote key fob? its the one where the key flicks out.
|
|
Push a small screwdriver in to the slot half way down the back of the key. Pull the two halves of the key apart and get access to the battery.
|
I got a new one fitted at the parts desk of my VW dealers.
No charge for fitting. IIRC though the actual key part needed to be removed with considerable effort before splitting the electrical bit.

I've found the same problem trying to open my VW key fob.
But I wouldn't buy the battery at a VW garage - it will be at least six or eight times more expensive than it should be.
Find out the type of battery required and then go to a battery specialist; could even be cheaper ordering on-line...:-)

PS
A pack of 36 watch or similar use batteries at my local B and M store (six each of four types of common batteries) costs 99p.
They last between nine and 12 months in each of the three watches I use over the course of the week.
Price to fit at a watch shop - £2.50 for the basic type and £6 upwards for litium etc.

The battery at the VW dealer was a very reasonable cost, around a pound.
Aware of the £1 battery multi packs - I buy them myself but their shelf life and operating life is poor. They are certainly not long life lithium cells.

>>They are certainly not long life lithium cells.>>
Where exactly did I state that they were?
They are good enough for the purpose I use them for - i.e. keeping quartz watches keeping spot on time for almost a year.
Many years ago my wife was chairman of the local school governors and we used to visit Manchester's Cheetham Hill district to buy prizes etc for the regular fund raising events.
Quartz watches could be bought for around 35-40p each and packs of three or four batteries for about 50p - in the shops the watches would be from £2.99 upwards.
Preston's Tradex cash and carry outlet sells excellent refillable cigarette lighters with piezo-electronic mechanisms in a retail pack of eight. Price per pack? 88p including VAT.
Price at your local supermarket for such a lighter is between 49p and 99p each.
As in so many areas, including cars, electrical goods, hi-fi, washing machines etc the Great British public has been ripped off for years, but for many the reality sunk in some time ago and have taken appropriate action.
Hence the panic in the retail trade over Christmas. Shops were selling plenty of goods, but essential discounting to attract customers meant that the profit margins were much slimmer.

I know the cheapos are not lithium.
I prefer a long shelf life and operating life.
For something that is easy to change the batteries in I use the cheapos -but a watch is very tricky unless you have got steady hands, perfect eyesight and the right tools.
The VW fob required a visible degree of skill and confidence such that I'd not be able to do the job myself.The price was right for the job.

There does seem to be a difference in quality in these small batteries.
I've always used the Mitsubishi black diamond 2032 for the car remote.
last time I bought a pack of two from WIlkos called Energiser.
They didnt last five minutes and Wilkos exchanged them.
Have taken these out of the bubble pack and find on the tester the needle sinks to low in a couple of seconds. WIll use them but wouldnt buy again..
|
>>They didn't last five minutes..>
Very surprised at that - might/must have been old stock - again a surprise in the case of Wilkinson which has a high turnover rate (at least at my local branch).
At the same B and M store I mentioned earlier two Sony, Panasonic or Mitsubishi D cells are 59p a pack - same price for two C cells and eight Sony AAs are 99p.

It is most unlikely that car key batteries are specially made for VW or any other car. It is much more likely they are just a standard battery, albeit selected for the right sort of capacity.
Thus you need the type number and then buy either the same make or one of another manufacturer. Yes, like anything else, you can get lower quality parts if unlucky.
A Lithium one provides a voltage of about 3.3 - 3.6 volts. Alkaline provides a voltage of 1.5 volts or so. Either of these usually has a good shelf life. Watches almost always use Alkaline, car keys seem mostly to use Lithium (the ones I have seen). It is easier to design circuits using 3.3 volts than it is to use 1.5 volts. You need to buy the correct type, as described by its type number. They are not interchangeable.
As for simple battery testers, unless the one used was specially made for that size of battery, the result can be questionable. Simple testers usually load the battery while indicating the voltage as bad-good, red-green, and the loading used may be too great for a small battery to give a good account of itself.
Make sure you put the battery in the key the right way up.

The car key design will be created around a particular battery size and capacity - no point in doing otherwise - that will have a reasonable lifespan.
My Bora's key battery is the same one as when the car was acquired nearly two years ago and is still going strong; the spare key has never had to be used.
But it could well be time to be thinking of buying a spare just in case.....:-)

Apparently it's important to complete installing a new battery within approximtely a minute (presumably to retain the settings).

Hi. Put a small screwdriver in the slot on the opposite side from the buttons and twist so that the fob splits into two parts, one with the key and one with the buttons. Split the button side at the seam furthest away from the buttons. You can then prize the batteries out of the casing. You'll need 2 x CR1620 Lithium Batteries. HTH - Andy

I know it's a late post, but for others doing a search and ending up here, the above message from Rhubarb is perfect.
One note though. My fob uses a single CR2032, a very common big disc used by computers. I can get 3 for CDN$1.00. Beats the $8 the dealer wanted to charge me.

The dealer told me that in the new BMW Key Free key fob type things, the batteries are recharged when in the slot on the dash. Hence no need for new batteries.
He advised swapping the spare & original key (they are identical) from time to time to keep both batteries in a healthy state.
