..........and ya, where did u get the car battery from. if the indicator light on the smart key flashes when u press the bottons the nothing is wrong wit the key. it could be the car battery. even the little difference in battery voltage can cause different problems. so please check u'r battery.... but if u gat the battery from the stealership then take it back to them, be little mad, ask for the manager, yell at him, u'r rest of the problem will be on the house....

have you put the key back in the ignition yet?

Once you do that, it should work fine.
