This is an interesting subject. None of our fobs will last for ever. The battery has a finite life and as time goes by more of us will begin to see fobs fail. There's no reason to dispose of the whole fob when the battery fails. If we can get into them without destroying the case it will be possible to replace the battery - it is highly unlikely to be a battery unique to Landrover.

If its Capacitor it should be good for life.

Do you have 'key insurance'? you often get it lumped into a bank account or car insurance policy. If you have and you 'lost' your key they would provide you with a new set... |

It's possible to do it with a capacitor but the power requirements of an RF transmitter would normally mean that a capacitor store supply would be unsuitable. For one thing, the discharge curve is nearer linear meaning you'd soon run out of charge after a few presses without docking. A battery (Li-Ion, NiMH, LiPolymer) has a near flat discharge curve, dropping off rapidly when near depletion. Do you have a link to any info on the internals? I'd be very interested to see inside but not so interested as to attack my own with tools! |

Hi lar Your English is good and accumulator is defined as ... accumulator noun 1 elec engineering a storage battery that can be recharged by passing a current through it from an external direct current supply. The best translation I can give you is ... The battery is recharged when the engine is running. 09 HSE Auto Lago Grey/Almond Napoli. Privacy glass. |

How long does it take to re-charge, I have a spare that will only just turn off the alarm but as I only do short journeys I dont think that I can get it fully charged.

by capacitance I guess same as an electric tooth brush. a coil in the fob and a coil in the holder At work

Inductive charging.. I've heard you can use an inductive charge mat to charge your car keys!! Works the same as the BMW key...

Oh and anyones tempted to buy a spare key of tatbay... I''ve heard that the key can only be programmed once... so if you find one advertised as needing 'reprogramming; or if its been used on another car, leave it as you cant reprogram them Freelander 2 TD4 Auto, SE, Narvik Black, Alpaca full leather, Rear Headrest Entertainment System, 6 CD, 18 HSE Wheels, Privicy tints |
