all sorted, update on central locking not unlockin

for those of you who didn't read my other thread, had a problem where if the Jimny had been standing for a while (like over night) the unlock function would not work unless the lock button was pressed first

had a look around on the web and found one other with the same problem, which had started only after Suzuki replaced the key fob battery as it had died. It didn't state the fix, but there was a link to some company

however, in the above case, Suzuki hadn't used the recommended battery, but had used a cr2303 (or something like that), but what the heck, still a 3V battery

had to get a replacement kettle on Wednesday and while at Asda, had a chat to the guys in the shoe repair place, who can not only do watches, but have all the gear for testing key fobs too. Explained the problem, key fob tested and was sending out signals on both lock and unlock functions. Took out the battery (knowing he only had 20 seconds to test it)
and it was good, in the green, but on the lower end of it. The only thing they cant measure is the signal strength6

charged a tenner for a new cr1616 battery and hey presto

yes, this really was the problem, a low battery, but not understanding why the symptoms, ie lock would seem to wake it up then the unlock would work.

he also said there were about 30 different types of 3V batteries available and I'm thinking that's why the other guys didn't work with a new battery, not enough oooomph in it as the wrong type

so there you have it, live and learn

Glad u sorted it but a tenner for a battery like that i wouldnt go there again

What's this 20 seconds thing? My battery(CR 1616) was out for hours and it was no problem?? 08 reg.
A good brand battery can be had for around a fiver! Other unbranded much less
It went again a few months later so I assumed it was cheap batteries but I removed the rubber button cover and cleaned it although I didn't see any evidence of dirt I also carefully prised up the tiny "T" shaped earth contact under the battery and it was all ok again.
Sweat or body grease might be the culprit?? Try not to handle the contact surfaces on the battery or clean using the swabs you get for cleaning glasses.
The rubber button parts are easily available on ebay.
