lost keys

The cheapest and easiest way are not the same.

If the key does not have a factory immobilizer, the cheapest way is to remove the lock cylinder from the passenger door and take it to a lock smith or dealer to have keys made.

If the car does have a factory immobilizer, you will have to get the car to a dealer to have a proper key made. Prepare to spend lots of money.

The easiest way is to have the lock smith come to you.

As far as the separate immobilizer, if it is an aftermarket unit, then you have to go to the aftermarket dealer to have a key made. If you do not have installation instructions, be prepared to spend lots of money to remove it.

thankyou for your reply. is there any particular way of telling if a key is chipped? save us the expense of ordering one if no need. crossed our minds that this happened before, so they may have had built in immobiliser disconnected and had normal key, thats why seperate immobiliser fitted?

It depends on the year, model, and country where you are. A Toyota dealer can tell you what year the keys started coming with chips, if at all.

It is not easy to defeat the factory immobilizer (which is the point of the immobilizer). More likely reason for a separate aftermarket one are a) the previous owner didn't realize that the car already had one; b) the previous owner was very concerned about theft; c) the previous owner succumbed to a salesperson's pitch

The lock number is stamped into the passenger side door handle/lock (have to take inner door panel off and remove handle) --- so rather than taking it to a locksmoth when you remove it (probably $50) take the number to a Toyota dealer and they will cut a new lock to than number. A Curtis key is like $5 while a Toyota OEM one (NO chip) is $10-15. If it indeed takes and OEM tranponder key - you'r stuck buying a new $60 key plus an expensive new ECM - and then having it installed and programmed.
