kidneystone Posted January 1, 2018 Share Posted January 1, 2018 (edited) Take the car down to Harrolds, they will tell you what is wrong with the fob. http://www.hharrold.co.uk/ Oh just noticed you are in Chesterfield, look for a local one.

El Cid Posted January 1, 2018 Share Posted January 1, 2018 My Rover 25 spare fob does not work : battery OK . Do you buy a new one and re programme ? Where from : how ? https://www.ebay.co.uk/itm/OEM-2-BUTTON-REMOTE-KEY-ALARM-FOB-for-ROVER-MG-ZR-ZS-MGF-TF-25-45-etc-3TXB-/263237940401?_trksid=p2385738.m4383.l4275.c10 You need to know what you are buying. Sometimes they can clone your key, or they may need to plug their laptop into your cars CPU. A company came out to my Renault, reprogrammed 2 new keys and it took them less than 10 minutes, cost = £100 Link to comment Share on other sites More sharing options...
alan p Posted January 1, 2018 Share Posted January 1, 2018 Have a look at this site. ITSTILLRUNS.COM. They show you how to reset it. I haven’t used it so cannot guarantee it will work. Alan. Link to comment Share on other sites More sharing options...
zigzag Posted January 1, 2018 Share Posted January 1, 2018 Are you 100% sure the battery is good and in the right way around ? with the key out of the ignition press the unlock button multiple times it should sync if it is working , on some models pressing both unlock and lock buttons does the same trick.If this fails take it to lock smith (harolds is best) and they will check that it is sending a signal .If its dead it will be cheaper to buy an ECU /alarm module/fob set from ebay .You need all three as they are coded together ,about £30-£40 easy job to change takes about 20 mins . hope this helps.
