Thread: Discovery 3 Key remote

I believe during certain services they actually replace the rechargeable battery. Read it somewhere but can't find it. Always the way. Shouldn't need a whole new key.

I have read on Disco3.co.uk someone pried theirs apart and unsoldered the old battery and resoldered a replacement chargeable battery. The case then needs to be reglued together.

I have not tried this so please let us know.

I also have one key where the battery is dead.

I have been told by a reliable source that the key charges while in the ignition so you should use both keys at different times to maintain them in good order. Hope this helps.

My one that died was the one I used every day. The spare that was in the cupboard and unused for 4 years worked fine.

You are right though they do charge when in use.

I have recently replaced the battery in my spare, bought a new empty FOB off Ebay, a new battery from the UK, all up cost around $25. Prised open the old FOB, replaced the battery (fiddly) and put the new case together with Superglue (fiddley as well). Had to use my Faultmate to have the vehicle relearn the key and all is well.

Same with us the everyday key is the one that died and the spare works faultlessly

Here is a link to tear apart instructions re the key fob. It is not easy, but the incentive is high. It may be that just the solder joint of the battery to the circuit board has cracked - seems common. In other words, perhaps re solder the tab to the circuit board and then tie the key fob, (elastic bands), to the working key fob for a couple of days of driving and all may be OK again.

The rechargeable vanadium pentoxide lithium battery that you purchase is Panasonic 3 volt VL2330 1HFE but the number may now be changed to VL 2330 HFN. The 1HFE refers to the style of tabs that are soldered on and that there is an insulation wrap around the perimeter of the 23mm diameter coin type battery. You will probably have some difficulty actually getting the battery. The best source in the USA is Digi-Key and they will sell one or two and mail them to you at a fair price.

If you just replace the battery, the existing programming should be OK. It is when a new key fob from Solihull shows up that reprogramming of all your keys is required.

hello,

Having the same problem but my key works for a couple of days if I drive car but two days without use it's dead.

I have a D3 2005 would I also use the VL 2330 HFN?

Thanks
