About BMW E46 Key
Ever since 1916, BMW, one of the best-selling luxury automakers in the world, has striven to design aerodynamic, luxury vehicles that excel in both performance and stability. For all BMW 3-series vehicles, a BMW E46 key can be purchased as a spare. Find a large inventory on eBay. Each key needs to be programmed before it functions and syncs with its respective BMW vehicles. To program the BMW E46 key, get in your car, and place the key in the ignition. Turn the key to the on and off position quickly five times. Hold the unlock button down while you simultaneously push the lock button three times. Your BMW vehicle should lock and unlock, which is a signal that the programming has been completed successfully, and the key can be used. Each BMW E46 key has a battery life of approximately three years, so consider adding a BMW E46 key battery to your purchase. If you need to replace the outer case due to damage or unsightly scuffs, replacement BMW E46 key cases are also available.
