BMW 320 E46 - the central locking with the remote does not open the door

Hello
There was a problem with opening the central lock with the remote control, I did measurements of currents because I was discharging the battery, which made it necessary to unfasten one with the battery clamp. After a few such measurements the pilot from the central lock stopped working, so I thought that it could decode, unfortunately the attempt to rewrite the code a few times did not give the central lock is efficient because it unlocks the inside of the key without any problem, not enough after re-downloading the keys for a moment. battery, the remote control normally works until the key is inserted into the ignition and the car is turned on, then as if the memory was canceling and the programming key is not going again or the pilot does not work, the rest without charge, any time I unhook the klem. What could be wrong with any of you having a similar problem ??? I will change that I have only one key, the rechargeable battery from the remote control is in working order, the relays from the comfort module rather have nothing to do, because the central works without any complaints and from the console and from the lock. So I do not know what else I can check?

Coding the remote control to the effect!

And any more rational solution ??? because it's as if he wrote, I do not open the door with the lock insert and answer that I would hear the key spin until it works. Normally the key should be coded right away, but I've tried to do a great deal a dozen times and nothing.

Well, there is a fundamental difference between the mechanical lock and the electronic lock. The first one has a normal switch - a switch, in the other a radio receiver and a remote control. Maybe you have any errors in the key coding algorithm? or an error in a complex electronic module? It would fit the diagnosis of this element. The original key? How I sclerosis is not mistaken there are two ways - types of coding. I do not remember the more sins.

Stop disconnecting the cache and do some computer diagnostics.

I was yesterday I connected the car to the computer I had a lot of errors, but there was no time to check what is just deleted what we could, because a lot could have been caused by recent measurements and fuses, after erasing errors, I still do not work, nothing has stopped working after downloading the clamp. now only from the insert. The key is original, after that I tried to erase the errors a dozen times and program them without any effect. Any ideas ?? where is the code from the key in the radio receiver in the post or comfort module. Maybe this receiver has died ?? but no wonder, because before everything was working fine, only after the measurements something shot, maybe some short circuit I did: /

How do you code the key? Describe what you are doing.
And finish with this tribe, because you will not get rid of mistakes.

I get in the car I turn the ignition switch to position 1 I wait about 5 seconds I pull the key and hold the button with the logo and press the door opening button three times, performs several attempts the same way I do the reverse holding the door opening button and I press the stamp with the logo, i.e., from closing the door. I have locked doors that are not locked, I do not touch anything at this time. not once coded it always went out. I also read that when you open the zipper from the insert, you must wait about 15 minutes and then you can try. miracles wreaths and nothing.

Ignition key in a maximum of 5 seconds. After pressing the opening button 3 times, of course, you release the closing button?

That's a maximum of 5 seconds, after I release the closing button and vice versa I did it without releasing the button, different ways

I bet the pilot damage.

I will go to the key man next week and I will check my key and whether he will be able to code it
