Title: Key coding
Post by: guest2866 on December 28, 2012, 09:23:26 AM
Is it possible to code a new remote key fob with only having a manual key as the remote one has been lost

yes, something like:
Quote
the actual remote to operate the door locking is programmed by:
 switch ignition on
 Press open button
 ignition off
 ignition on
 press same button
 ignition off
 ignition on
 press same button again
 ignition off
 ignition on
 press the same button twice again and you should hear the door locks operate.

edit: I actually did it with the fob from ebay and it works ok

I am just wondering does this just program the central locking or will this also make the transponder work as well?

I am getting a new key and I had a look today and the transponder chip looks like its being held in place with some glue. I will carefully try and remove it but if I break it what are my options? And are the chips easy to damage?

No, those chips are amazingly robust.  At the locksmiths they are kept in little plastic bottles and the guys just jam them in the slots in the keys.  I think the working parts are encased in an epoxy shell, so you could stand on them without trouble.

The chip is for the transponder.  The electrical circuit activates the central locking

Thats good to know that they are a bit robust. I have googled it and a lot of posts I found said they were rather fragile.

Some Renault chips are long and narrow, I imagine these might be fragile, but most are tiny square housings and clip into the side of the key.  The shop import Chinese chips for many cars and they are steadily coming down in price.  The early ones were $45 each, now it is 10 for $30.  There is a tremendous markup on these chips.  A Mercedes Benz dealer might charge R1800 (£150) for a blank chip which the shop buys for $3 and sells for R300 (£20).  Of course you have to encode it and there are about 10 different machines with dozens of adaptors.  Very little, if any standardisation.  Renault again are the worst, 10 Renaults might have 4 different plugs.  Only the French could do that.

If you're trying to swap transponder from old key into new one you don't need to program it again.
If it's new key with new chip, then yeah, last summer local honda dealer charged me £28 to program 2 keys. I could not find any car locksmith willing to do it cheaper at the time.

I got the flick style key cut (that I got off ebay) yesterday but annoyingly it does not fit the lock for the car. Is it worth going back to where they cut it? Is there anything they can do?

mm, yes they should fix it.

I've ordered mine on-line from carkeyhelp, they cut it from photo but got it wrong first time because of human error, I've send keys back for recut, works now, ish (one of keys won't open fuel cap, probably needs a little bit of sanding)

Depends. Does it physically not fit in the lock or does it fail to lock/unlock?

Does anyone know it only programme the remote only or the transponder too?

only remote
programming transponder requires some honda specific software
auto locksmiths could do that, but honda dealer was cheaper for me

just a silly question is that mean I need the key cut before I can program the fob? I only got 1 keys at the moment can I stuck the only key in the car and program the 2nd fob?

Thanks
