Replacing Faulty Chips

pghdr chipping

Sometimes microchips do fail.

The nature of the technology means that some chips do fail. Fortunately this is a very small percentage of chips. Chips can fail for a number of reasons, but it is also important to note that in many cases, the chip may not actually be the problem. Other issues can include migration, low battery level in scanners, low quality scanners, scanning too quickly and even, metal near the scanner.

This uncertainty about whether the chip has failed permanently or whether another factor may be responsible is why the NZCAR allows up to THREE microchip numbers to be recorded.  We also ensure that all THREE of these numbers remain fully searchable just in case the apparently "failed" chip starts working again, or incase the pet has been chipped multiple times.

What to do when a chip has failed

If you are replacing a chip in an animal registered with the NZCAR we ask that you notify us by fax or email with the following information:

  • the faulty microchip number,
  • the new microchip number,
  • the owners name,
  • the pets name.

These four bits of data allow us to locate the record and update it to ensure both the old number and new number are linked. Should either number be searched it is important the correct details are displayed.

There is a $5 fee for updating the database in these circumstances, chargeable to the implanting clinic. This cost can usually be recovered from the chip manufacturer.*

If the faulty microchip is not already registered on our database, and the owner wishes to register their pet on the NZCAR, then just complete our normal microchip registration form, noting the faulty microchip number, that it is a new registration, and send it to us. The standard registration fee will apply in these cases.
