Evening all.  Tried to unlock car using both keyfobs, red light on fob lights up but doors dont unlock.  Didnt have time to look at it as was running late & managed to get a lift to work.

 

Im guessing you can remove the keycover.  2014 plate octavia mk3 - is it likely to be a battery issue? 

 

How long should the batteries last  - does 6 years sound about right?

 

Assuming I need to replace, whats a good suggestion? Im guessing it needs to be a start/stop battery - not sure of the difference between AGM & EFB.  Not after anything too expensive as will probably be selling the car in the next 2-3 years.

 

Ive got a 1.4 TSI

 

Thanks

Yes the small cap on drivers door handle comes off to reveal the lock, you can use the key blade.  I suppose gain entry, check battery, charge (if dead) and see if it all works (and how long it lasts).  Either something has drained the battery or like mine it literally gave up overnight.  My battery on my 65 plate Octavia lasted 3 years so you've done well.  I just got like for like AGM Halfords own brand and fitted myself, it came with 4 year guarantee and at time of selling a few years later it was fine.

 

You are supposed to tell the car the battery has been changed (VCDS OBD etc), its less of an issue I believe if its like for like - i didn't do mine and i didn't have any problems.

Thanks Scout.  Breakdown service we get through Nationwide BS came out this morning - confirmed battery is on the way out.  

 

Halfords fit an AGM battery for £184 including sorting the computer so will book that in for tomorrow.

Fairly sure thats the battery I got  - Out of curiosity ask them what they do when they 'sort the computer'.
