I think I might just have a solution to this now....
I have met this guys through ebay who sell the REMOTE KEYLESS ENTRY CENTRAL LOCKING KIT for HONDA JAZZ CRV for just £25.
That cheap but since I can't fit/install it, he has introduced me to another guy (auto-electrician) who will fit it for £75.
I have been leaving my car unlocked which can be very serious if people spot that they can enter.
The other day that I spoke to Honda, they were quoting around £130 for the parts alone and even if they replace the barrell or tumbler of whatever, from other's experience, it can happen again.
As this model 1.4 S do not come with remote key, if the guys install this and it works properly, it could be what I have been wanting for sometime ...for £100
