Suggestion
IF the fob is unsync'd, you can check/reset using one or more of the following:
Leading evidence: 'Check /' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check /' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

Suggestion
As the remote uses a rolling code (new code every lock cycle) if the remote sender has been activated more than 256 times and less than 1024 times with the receiver out of range or while the vehicle battery is disconnected the unit must be resynchronized as follows:

Use normal button (cr) battery like many calculators, watches etc

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

My spare key has stopped working. Spoke to the Porsche garage and he was going on about transponders and recoding both the keys at a snip of a cost of £180. Are there any alternatives or do I bite the bullet?
The car receiver (and other circuits) go into "sleep" mode after 5 days.
To wake, simply unlock car using key in lock. The car will awake, lock/unlock using remote again to turn off alarm.
If key fob is at fault (or no battery), you have 20 secs to turn on ignition after opening door before alarm goes off and it will be disarmed.
If your fob is either unsynchronized or dead it requires a replacement and is about £85 including reprogramming.
IF the fob is unsync'd, you can check/reset using one or more of the following:
The remote uses a normal button (CR) battery like many calculators, watches etc.
CR-2032 (20mm diameter by 3.2 mm thickness)
I think they are £1-£2 from Wilkinsons, Boots WHSmith etc
Just carefully prise open fob and swap over. I think it is easier to align rubber button downwards and then click "lid" over the PCB. Otherwise I found that doing it the other way resulted in the "lid" (the other lid this time!) not quite aligning with PCB, leaving a gap.
Porsche advise any remote range of 5 ft or less suggests new battery is required.
RESET PROCEDURE
Reset by manually unlocking the car door and whilst the key is still in the door, press the button, lock/unlock button. This re-syncs the electronics if it is time that has caused the car to forget the remote.
As the remote uses a rolling code (new code every lock cycle) if the remote sender has been activated more than 256 times and less than 1024 times with the receiver out of range or while the vehicle battery is disconnected the unit must be resynchronized as follows:
- Switch on the ignition (ignition key must have the correct transponder).
- Switch off the ignition.
- Remove the key and press the remote sender button within 6 seconds after the ignition key has been removed
The activation counter will then be reset to zero.
If the fault lies with the remote, you can reset the remote fob's chip by inserting the button battery in reverse (wrong way round) for a couple of seconds. (ie -+, +-)
If none of those work, you probably need a new remote!
If you are buying three I can do a discount.
The reason it's £20 is that I need to save up enough to buy the 998/991 as soon as it comes out.
That way I can get ahead of the curve for dismantling and taking pictures for the next edition.
