SKC Posted October 22, 2019 Share Posted October 22, 2019 Hi All,Got an R500D in at the moment. These cars feature keyless ignition, just an immobiliser.Appear to be having an issue now to get the immobiliser to turn off, does anyone know if there is a battery in the immobiliser fob that may have gone flat?Failing this has anyone else experienced this and if so what's the fix please.RegardsSKC.

Member Jonathan Kay Posted October 22, 2019 Member Share Posted October 22, 2019 Can you add a photo of the fob, please?Jonathan Link to comment Share on other sites More sharing options...
SKC Posted October 22, 2019 Author Share Posted October 22, 2019 Hi Jonathan,Thanks for the quick response.Unfortunately at the moment, I can't. The car is at the rolling road, fortunately just finished calibration work.RegardsSKC Link to comment Share on other sites More sharing options...
ChrisC Posted October 22, 2019 Share Posted October 22, 2019 Is it the Sterling Excel unit? I just checked the owners manual for that unit, and there is nothing about a battery in the fob. Any chance the antenna in the tunnel cover has become disconnected? Link to comment Share on other sites More sharing options...
Leadership Team Shortshift Posted October 23, 2019 Leadership Team Share Posted October 23, 2019 Hi Stuart - there is no battery internal to the unit. I have sent you a blatmail...James Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted October 23, 2019 Member Share Posted October 23, 2019 Does it look like this?Jonathan Link to comment Share on other sites More sharing options...
Leadership Team Shortshift Posted October 23, 2019 Leadership Team Share Posted October 23, 2019 That's an old Vecta key, I believe, Jonathan. My R500D (only a couple of years newer than the one that Stuart is talking about) has the Toad system which utilises the battery-less oval-shaped transponder that many of us are familiar with.I've sent Stuart a BM simply because it's sometimes best to share 'security system knowledge' away from public gaze... A tricky one as I'm a great believer in the use of BC to share experience and knowledge!James Link to comment Share on other sites More sharing options...

Leadership Team Shortshift Posted October 23, 2019 Leadership Team Share Posted October 23, 2019 Good man Jonathan - the correct word for the three-dimensional representation of the two-dimensional oval form!!But maybe it's actually more pearl, or even lozenge, shaped...James Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted October 23, 2019 Member Share Posted October 23, 2019 :-)Could you add a photo? (I have documentation and there are previous discussions on several types of immobilisers but (obviously) I don't know how to identify them or which Sevens had which.)Jonathan Link to comment Share on other sites More sharing options...
Leadership Team Shortshift Posted October 23, 2019 Leadership Team Share Posted October 23, 2019 I'm afraid I can't at the moment, Jonathan, as I am not at home. But maybe Stuart can...James Link to comment Share on other sites More sharing options...
Leadership Team Shortshift Posted October 23, 2019 Leadership Team Share Posted October 23, 2019 However... here's a stock photo of the Toad/Sterling Exel immobiliser system showing the two oval/ovoid/pearl/lozenge shaped fobs:The black plastic box is encased within the metal cover and, on my R500D at least, is mounted to the cabin (inside) surface of the front upper bulkhead in the passenger area. The circular wire loop is the part that the fob/transponder has to pass through in order for the immobililser to be deactivated. On my R500 (keyless) this loop is positioned in the upper front area of the centre console but I know that on many other cars it is loosely coiled around the steering column mounted ignition key area so that the fob (attached to the key) passes through the loop when the key-on position is selected.James Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted October 24, 2019 Member Share Posted October 24, 2019 That's the way to do it. :-)SKC: is that what you've got?Jonathan Link to comment Share on other sites More sharing options...
ian3 Posted October 24, 2019 Share Posted October 24, 2019 I've got an email from Caterham somewhere giving instructions on how to program the key as they can forget how to work !If that is of any use to you let me have details and I will send.(Mine certainly looks the same and is a 2009 R500 D)Regards,Ian.
