replacing the complete lock set with the EWS control unit can be expensive as the control unit will also need to be programed and/or encoded, however if the lost keys cannot be found and you are sure they cannot be used to steel you car you can just order replacement keys from your local bmw dealer. hope this is of some help. You will also nead to disable the lost keys if you order replacements rather than a complete set.

SOURCE: BMW 525i will not start
There are six fuse panels for an E39 BMW
Fuses F1 - F45, fuse panel 1, glove compartment. Twist white plastic retainers 90 degrees and pull down from top of glove compartment.
Fuse 31 (10 amp) protects fuel pump relay(K96)
Fuses F46 - F6, fuse panel 2, trunk located behind right side luggage compartment interior panel.
Fuse 54 (15 amp) protects fuel pump relay(K96)
Before I would do any of the following, I would check the above fuses and put a bottle of HEET into the fuel tank. Fuel filter changing is not hard, but it will take you about an hour.
The fuel pump is another story (BMW has a special spanner wrench(16 1 020) to remove and install the threaded collar.
E39 BMW use a two-lobed fuel tank(think saddle bag like). Each with its own fuel level sending unit that has a float connected to a variable resistance wiper contact. To equalize fuel level between the two tank lobes, a siphon pump is installed in the left lobe. The resistances need to be approximately the same. The fuel pump is on the right lobe under the tank sending unit beneath the threaded collar at the top of the fuel tank which is accessed by removing the rear seat cushion. WARNING When removing the fuel level sender or the fuel pump, the fuel tank should be drained to 1/4 capacity or below. The fuel in the fuel line is under pressure (45-75 psi). Always unscrew the fuel tank cap to release pressure in the tank before working on the tank or lines. Disconnect battery negative cable.
The fuel filter is located beneath the center of the car near the driver's seat usually under a protective metal cover held on by small screws. Not hard to replace but car will need to be on jack stands and 1/4 tank or less of fuel in the tank. Definitely wear safety goggles or face shield as the fuel will come out on face. Have a fuel catch pan under the filter. Clamp the fuel line before and after the fuel filter(long metal cylinder) before loosening hose clamps. Loosen center clamping bracket and hose clamps on either end of filter. [Some have an inline fuel pressure regulator.(Remove vacuum hose, pull out locking clip, remove fuel pressure regulator).]
Drain fuel from inlet side of filter and check fuel for rust moisture or other contaminats.
Installation is reverse. When installing fuel filter, ensure fuel flow direction arrow points to front. Should have at least 5 liters of fuel in tank before restarting. The fuel pump will be damaged if run without fuel.

On the instrument cluster in the center there are two buttons (clock and s/r) .Press and hold the s/r (i think thats whats on the button) and turn the key to the first position. at first it will say TEST in the cluster. keep holding the s/r button and it will flash to your SIA (service meter) release the button and press and hold until it says reset (or reset flashes) and then press again. just play with it im going off of memory. just dont be afraid. as usual im sure your local bmw dealership would be glad to help

I would say replace ignition coil, that might me the problem, otherwise it can be the ecu, which might have some electrical problems not allowing the car to stay running. Good luck.
