Thans for advice Gord,but no luck-or maybe i didnt explain properly..i picked up this IS200 approx a week ago,43000 on the clock but batt totally dead. Its a minter (t-plate '99). I put a new batt in but have come across two probs,(one a sat nav prob-but thats a new topic)..the key would only just open doors but only when held agaist the receiving sensor so thougt i would replace batt in master key(only key i have) but,being a Lexus virgin didnt realise(till told by man in shop) that there may be a time period/limit between swoppng batts that may affect it.
On trying new batt in key it would open only drivers door,start engine but nothing more!
The next day it opened all doors,and locked,and at distance via key especally after starting car,but now wont.
No cenral lockng with key in door either but still starts! Have i left it too long between batt changes? If so what can/should i do to reassociate the key with car?
