Frequently Asked Questions mentioning E52
Looking for the V23078-C1002-A303 relay made by Siemens/Tyco?
What can you fix?
I mainly fix BMW diamond
shaped key fobs where the remote function has stopped working, but, still
starts the car. Before sending in any key make sure it needs repair. Try
syncing the key to the car first, key sync
procedure. If key sync does not work or it works, but, soon stops working
and needs to be sync'd again it probably needs to be repaired. I also repair
keys that won't start allow engine cranking. I do not do cosmetic repairs. If
the round BMW logo is missing I will not replace it, but, you can buy new ones
from BMW. For diamond shaped remotes used with E38, E39, E46, E52, E53 the part
number is 66122155753. For the rectangular remotes with hidden key blade for
E60, E61, E63, E64, E82, E88, E90, E91 and others, the part number is
66122155754. They should cost about $10. The -753 part is 11mm is diameter with
a adhesive flat back and clear domed rubber front. The -754 part is just a
pieces of stamped aluminum with a slightly concave back and painted
front.
How much?
For keys that have not been cut
open, repair is $60 including return shipping within the US or $70
including return shipping outside the US. For keys that have been cut open and the original battery has been
modified, add $25. For keys that have been
cut open and the original battery has not been modified in any way,
add $15. Why the extra fee? Well because I get a lot of keys that are messed up
and fixing the damage takes more time than repairing the key in the first
place. I have taken pictures of some of the damage I have found in customers
keys and have posted them here on my key fob wall of
shame.
Want it repaired right away?
I can also repair keys if you bring them to me
in person. I'm a Los Angeles suburb called Torrance. Most keys are repaired in
about 40 minutes, but, some take longer if the problem is hard to find. Pricing
higher though, $75 for keys that have not been cut open, $15 extra if the key
has been cut open and $25 extra if the key has been cut open and the original
battery has been tampered, modified or ruined. Most keys I get in for repair do
not need the battery replaced as the problem is NOT the battery. This is not a
key fob battery replacement service! This is a key fob repair service, not a
battery replacement service. If the battery is the cause of the problem then it
will be replaced.
