Have Toyota Questions? Ask a Mechanic for Answers ASAP
Hello and welcome to just answer and allowing me to assist you. Sorry to hear of your problem but hopefully we can solve it . Don't use heavy grease but a light spray grease such as lubricate lithium grease or synthetic spray grease. aia think your problem is more of an adjustment then lubrication, you need to access the little 10mm head bolts holding the latch. Just remove the plastic garnish over the latch on the bottom of the trunk by lifting it up and loosen the bolts holding the latch so you can lift it upward a little ,lock the bolts and try that.make sure there is no debris in the latch. Hope this helps you solve your problem and if you require further assistance I'll be happy to do so.
